Calculating wave speed frequency and wavelength khan academy answers?

If you want to calculate the wavelength you need to look at the period (in seconds) that it takes for a wave to pass a given point. This is called the period T. The period T is the time it takes for one complete wave cycle, from the wave crest to the wave trough.

The period of a wave is equal to the total distance traveled divided by the wave speed.

These two properties are closely related to each other. For example, the wavelength of a wave is equal to the distance between two adjacent peaks or valleys. If you wonder how to calculate the wavelength of a wave based on the wave speed, you can use the formula distance = speed × time. This equation works for any wave traveling in a uniform medium, such as water or air.

Wave speed wave length and frequency Khan academy answers?

For most non-dispersive waves (e.g. sound waves, water waves, or electromagnetic waves), the speed of the wave is equal to the square root of the absolute value of the pressure or volume gradient. As the wave “propagates”, its amplitude or strength decreases while its wavelength (distance between peaks of the wave) increases.

Wave speed frequency and wavelength calculation khan academy answers?

The wave speed is the speed at which the wave itself moves. Just as an object moving along the ground goes faster than an object stationary on the ground, a wave traveling through a medium or water will move more slowly than the same wave without any medium or water.

Another way to determine wave speed is to use the equation: V = F/T. This equation will give you the speed of the wave in meters per second. You will have to know the force that created the wave. Since this is not always easy to determine, you could also use the length of the wave to determine the speed. Doing this will give you the speed of the wave in meters per second. The equation to use is V = L/T.
