Q. How to determine wavelength of electromagnetic waves?
The frequency as well as velocity of a wave determines its wavelength the distance between equivalent points on a continuous wave. For waves of a specified velocity a wave with a higher frequency has a shorter wavelength. For electromagnetic waves this opposite relation is expressed mathematically by the following equation.
c = λv
In this equation c equivalents 3.00 *108 m/s the velocity of electro- magnetic waves in a vacuum equals the wavelength in meters and λ is the frequency of the waves in hertz.
