The wavelength for a wave propagating in air is given by:

$\overline{){\mathbf{\lambda}}{\mathbf{=}}\frac{\mathbf{c}}{\mathbf{f}}}$, where c is the speed of light and f is the frequency of the wave propagation.

Assume the following waves are propagating in air

a) Calculate the wavelength λ_{1} for gamma rays of frequency f_{1} = 6.30×10^{21 }Hz.

b) Calculate the wavelength λ_{2} for visible light of frequency f_{2} = 5.40×10^{14 }Hz.
