Question

00 points 1 out of 6 attempts In order to study the structure of a crystalline solid, you want to illuminate it with EM radiation whose wavelength is the same as the spacing of the atoms in the crystal (0.790 nm).

Explanation / Answer

a) frequency times the wavelength = speed of light. So, f=c/lambda or 3e8/0.790e-9 = 3.7974 e17 Hz
