The higher the frequency of the signal the shorter the wavelength. The formula for the frequency of a wave is used to find frequency f time period T wave speed V and wavelength l. The formula for time is.
Wavelength is the distance between the corresponding points in any two consecutive waves.
The number of waves traveled in one second is the frequency and the time period is the reciprocal of the frequency of the waves. Radio waves travel at the speed of light so in this case v is equal to 299792458 metres per second ms. Wavelength l 700 nm Velocity of light v 3 x 108 ms. The unit hertz Hz was once called cps cycles per second.
