Question

Gamma ray radiation falls in the wavelength region of 1.00×10-16 to 1.00×10-11 meters.

What is the frequency of gamma ray radiation that has a wavelength of 1.00×10-16 m?

Answer 1

$\lambda \nu=c$ where $\lambda,\nu,c$ are wavelength,frequency and speed of particle.

$c=3 \times 10^{8} m/sec$

$\lambda=10^{-16} m$

$\nu=\frac{c}{\lambda}=\frac{3 \times 10^8}{10^{-16}}=3 \times 10^{24} sec^{-1}$
