what is the equation used to calculate wave speed?

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.

The formula for frequency is: f (frequency) = 1 / T (period). f = c / λ = wave speed c (m/s) / wavelength λ (m). The formula for time is: T (period) = 1 / f (frequency).

Even though the wave speed is calculated by multiplying wavelength by frequency, an alteration in wavelength does not affect wave speed. Rather, an alteration in wavelength affects the frequency in an inverse manner. A doubling of the wavelength results in a halving of the frequency; yet the wave speed is not changed.

The equation for speed is simple: distance divided by time. You take the distance traveled (for example 3 meters), and divide it by the time (three seconds) to get the speed (one meter per second).

To calculate the speed of an object divide the distance the object travels by the amount of time it takes to travel the distance. Can be written as speed=distance/time (s=d/t ). The speed equation consists of a unit of distance divided by a unit of time. You just studied 27 terms!

Wave Speed, Wavelength, and Wave Frequency Wavelength is the distance between two corresponding points on adjacent waves. Wave frequency is the number of waves that pass a fixed point in a given amount of time. This equation shows how the three factors are related: Speed = Wavelength x Wave Frequency.

frequency x wavelength=wave speed. The frequency is inversely proportional to wavelength.

Wave Speeds P waves travel at speeds between 1 and 14 km per second, while S waves travel significantly slower, between 1 and 8 km per second. The S waves are the second wave to reach a seismic station measuring a disturbance. The difference in arrival times helps geologists determine the location of the earthquake.

In sum, the wavelength is inversely proportional to the frequency of a simple harmonic motion, while the wavelength is directly proportional to the speed of sound. This is expressed by the following formula: λ = c / f, where λ denotes the wavelength (in m), c denotes speed of sound (in m/s), and f is the frequency.

Wavelength and frequency of a wave are related by the equation Velocity = Wavelength x Frequency, where the velocity is the speed of a wave peak as it passes a stationary point. For all electromagnetic waves (in a vacuum) the velocity = c, the speed of light.

1 Answer. Chuck W. If you know the frequency of the photon, you can calculate the wavelength using the equation λ=cν where c is the speed of light and ν is the frequency.

What is the relationship among frequency, wavelength, and wave speed? Wave speed is frequency multiplied by wavelength. What is meant by the superposition principle? When two or more waves occupy the same space, wave displacements add at every point.

The speed of any periodic wave is the product of its wavelength and frequency. v = λf. The speed of any electromagnetic waves in free space is the speed of light c = 3*108 m/s. Electromagnetic waves can have any wavelength λ or frequency f as long as λf = c.

Solve the relationship between speed and wavelength for λ: λ=vwf λ = v w f .
49438
So v = f * λ or solving for λ, the equation becomes λ = v / f. Wave speed has units of distance per unit time, for example, meters per second or m/s. Frequency has units of Hz. Wavelength is measured in units of distance, usually meters (m).
