Measuring Waves
Any point on a transverse wave moves up and down in a repeating pattern.

The shortest time that a point takes to return to the initial position (one vibration) is called period, T. In this example, every vibration is marked with a short pause.

The number of vibrations per second is called frequency and is measured in hertz (Hz). Here's the equation for frequency:
f = 1 / T

The shortest distance between peaks, the highest points, and troughs, the lowest points, is the wavelength, .


By knowing the frequency of a wave and its wavelength, we can find its velocity. Here is the equation for the velocity of a wave:

However, the velocity of a wave is only affected by the properties of the medium. It is not possible to increase the speed of a wave by increasing its wavelength. By doing this, the number of vibrations per second decreases and therefore the velocity remains the same.

The amplitude of a wave is the distance from a crest to where the wave is at equilibrium. The amplitude is used to measure the energy transferred by the wave. The bigger the distance, the greater the energy transferred.

Example:
A radio wave has a frequency of 93.9 MHz (93.9 * 106 Hz). What is its period?
f = 93.9 * 106 Hz
f = 1 / T
T = 1 / f

T = 1 / 93.9 x 106 Hz
T = 1.06 x 10-8 s
