The wavelength of red light is about 695 nm. What are the frequency and period of this radiation?

Calculate the wave length for several examples of sinusoidal electromagnetic radiation:

radio, 1000 kilohertz, λ = ?

television, 100 megahertz, λ = ?

red light, 4.3 × 1014 hertz, λ = ?

blue light, 7.5 × 1014 hertz, λ = ?
