Wave Frequency:
<u><em>Wave frequency is the number of waves that pass a fixed point in a given amount of time.</em></u>
How do you find the frequency of a wave?
<u><em>To calculate the frequency of a wave, divide the velocity of the wave by the wavelength. Write your answer in Hertz, or Hz, which is the unit for frequency. If you need to calculate the frequency from the time it takes to complete a wave cycle, or T, the frequency will be the inverse of the time, or 1 divided by T.</em></u>
