# How to find period of graph?

To write a sine function you simply need to use the following equation: f(x) = asin(bx + c) + d, where a is the amplitude, b is the period (you can find the period by dividing the absolute value b by 2pi; in your case, I believe the frequency and period are the same), c is the phase shift (or the shift along the x-axis

## Consequently, what is the period of a graph?

The period is the length of the smallest interval that contains exactly one copy of the repeating pattern. So the period of or is . Any part of the graph that shows this pattern over one period is called a cycle. For example, the graph of on the interval is one cycle.

## Continuing on this line, how do you find the period in physics?

each complete oscillation, called the period, is constant. The formula for the period T of a pendulum is T = 2π Square root of√L/g, where L is the length of the pendulum and g is the acceleration due to gravity.

## With allowance for this, what is the period T?

A period T is the time required for one complete cycle of vibration to pass a given point. As the frequency of a wave increases, the period of the wave decreases. Frequency and Period are in reciprocal relationships and can be expressed mathematically as: Period equals the Total time divided by the Number of cycles.

#### Do Tsunamis move slow?

In the deep ocean, tsunamis can move as fast as a jet plane, over 500 mph (800 km/h), and can cross entire oceans in less than a day. The distance between waves is the wavelength. At the shore, most tsunamis slow to the speed of a car, approximately 20 to 30 mph (30 to 50 km/h).

#### How do you calculate waves?

Speed = Wavelength x Wave Frequency. In this equation, wavelength is measured in meters and frequency is measured in hertz (Hz), or number of waves per second. Therefore, wave speed is given in meters per second, which is the SI unit for speed.

#### How tall can a tsunami get?

In some places a tsunami may cause the sea to rise vertically only a few inches or feet. In other places tsunamis have been known to surge vertically as high as 100 feet (30 meters). Most tsunamis cause the sea to rise no more than 10 feet (3 meters).

#### How fast do waves travel in water?

While they are in deep water, far offshore, the slowest wave components with the shortest period and the smallest distance between crests could be traveling at less than 5 miles per hour. The components with the longest periods could be moving at more than 35 miles per hour.

#### Who named Tsunami?

In Japan, the first recorded use of the word "tsunami" occurred well over 1,000 years ago. Tuesday, a boat lay aground after being washed inshore near Sendai. The word "tsunami" is originally a Japanese word, but today it's commonly used in English.

#### What is the world's worst tsunami?

At 7:59 AM, a 9.1-magnitude earthquake—one of the largest ever recorded—ripped through an undersea fault in the Indian Ocean, propelling a massive column of water toward unsuspecting shores. The Boxing Day tsunami would be the deadliest in recorded history, taking a staggering 230,000 lives in a matter of hours.

#### How do you know if a tsunami is coming?

Early warning signs of a tsunami
One of the signs of a potential tsunami is the occurrence of a very large earthquake that lasts for more than 20 seconds. A more immediate and ominous sign of an approaching tsunami is a rapid and unexpected recession of water levels below the expected low tide.

#### When was the last tsunami in the world?

Recent Tsunamis
Tsunami of January 22, 2017 (Bougainville, P.N.G.) Tsunami of December 17, 2016 (New Britain, P.N.G.)

#### What tsunami killed the most?

The most devastating and deadliest tsunami was one in the Indian Ocean on Boxing Day, 2004. The tsunami was the most lethal ever to have occurred, with a death toll that reached a staggering figure of over 230,000, affecting people in 14 countries – with Indonesia hit worst, followed by Sri Lanka, India, and Thailand.

#### How far does a wave travel in one period?

In a periodic wave, a pulse travels a distance of one wavelength λ in a time equal to one period T. The speed v of the wave can be expressed in terms of these quantities. This relationship holds true for any periodic wave.

#### What are the 5 biggest tsunamis?

• Sunda Strait, Indonesia 2018: Java and Sumatra, Indonesia.
• Palu, Sulawesi, Indonesia 2018: Palu bay, Indonesia.
• Sendai, Japan 2011: Japan and other countries.
• Maule, Chile 2010: Chile and other countries.
• Sumatra, Indonesia 2004: Indonesia, Thailand, Sri Lanka, Maldives and other countries.

#### Where was the last big tsunami?

A powerful undersea earthquake that struck off the coast of Sumatra island, Indonesia, set off the 2004 Indian Ocean tsunami, also known as the Christmas or Boxing Day tsunami, on Sunday morning, Dec. 26, 2004.

#### How fast are tsunamis?

Tsunami movement
In the deep ocean, a tsunami can move as fast as a jet plane, over 500 mph, and its wavelength, the distance from crest to crest, may be hundreds of miles.

#### Has there ever been a tsunami in 2020?

On 30 October 2020, a significant tsunami triggered by an earthquake of magnitude 7.0 Mw hit the island of Samos (Greece) and the Aegean coast of the Izmir region (Turkey).

#### What is the fastest wave?

The first kind of body wave is the P wave or primary wave. This is the fastest kind of seismic wave, and, consequently, the first to 'arrive' at a seismic station. The P wave can move through solid rock and fluids, like water or the liquid layers of the earth.

#### Has the US ever had a tsunami?

Large tsunamis have occurred in the United States and will undoubtedly occur again. Significant earthquakes around the Pacific rim have generated tsunamis that struck Hawaii, Alaska, and the U.S. west coast. The most noteworthy tsunami resulted from the 1929 magnitude 7.3 Grand Banks earthquake near Newfoundland.

#### What is the wave speed?

Wave speed is the speed at which a wave travels. Wave speed is related to wavelength, frequency, and period by the equation wave speed = frequency x wavelength. The most commonly used wave speed is the speed of visible light, an electromagnetic wave. And that means that its speed can depend only on the medium.

#### What country has the most tsunamis?

Where do tsunamis most often occur in the world? Tsunamis occur most often in the Pacific Ocean and Indonesia because the Pacific Rim bordering the Ocean has a large number of active submarine earthquake zones.

#### Why is wave speed constant?

A point on a transverse wave moves fastest as it passes through the equilibrium point, slows down as it reaches the maximum amplitude, stops, turns around and increases speed in the opposite direction. If the medium is uniform (does not change) then the wave speed will be constant.

#### How far inland would a 1000 Ft tsunami go?

Most tsunamis are less than 10 feet high when they hit land, but they can reach more than 100 feet high. When a tsunami comes ashore, areas less than 25 feet above sea level and within a mile of the sea will be in the greatest danger. However, tsunamis can surge up to 10 miles inland.

#### What do you call the height of a wave?

wave is a called the crest, and the low point is called the trough. The distance between successive crests or troughs is called the wavelength. The height of a wave is the amplitude.…

#### What was the biggest tsunami in history?

A tsunami with a record run-up height of 1720 feet occurred in Lituya Bay, Alaska. On the night of July 9, 1958, an earthquake along the Fairweather Fault in the Alaska Panhandle loosened about 40 million cubic yards (30.6 million cubic meters) of rock high above the northeastern shore of Lituya Bay.

#### What is the formula for wave period?

The formula for period is T = 1 / f , where "T" is period – the time it takes for one cycle to complete, and "f" is frequency. To get period from frequency, first convert frequency from Hertz to 1/s. Now divide 1 by the frequency. The result will be time (period) expressed in seconds.

#### What is the first tsunami in history?

History of the Tsunami
According to the National Geophysical Data Centre, the first recorded tsunami occurred off the coast of Syria over four thousand years ago. When the island volcano of Krakatoa, Indonesia, exploded in 1883, tsunamis swept as far away as the English Channel.

#### What is one cycle of a wave?

One cycle of a wave is one complete evolution of its shape until the point that it is ready to repeat itself. The period of a wave is the amount of time it takes to complete one cycle. Frequency is the number of complete cycles that a wave completes in a given amount of time.
