# Problem: Assume the following waves are propagating in aira) Calculate the wavelength λ1 for gamma rays of frequency f1 = 6.30×1021 Hz.b) Calculate the wavelength λ2 for visible light of frequency f2 = 5.40×1014 Hz.

###### FREE Expert Solution

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.
