Question

Define wavelength and frequency of electromagnetic radiation. How these two are related with velocity? ​

Answer 1

Answer:

The wavelength λ and frequency ν for any wave is related by the equation, λν=v where v is the wave velocity. For all electromagnetic waves, v=c and hence, λν=c is the relationship, where c is the speed of light in vacuum.
