Answer

Correct option: C.
$3 \times 10^{18} \text { to } 5 \times 10^{22} Hz$

The frequency range of Gamma rays is $3 \times 10^{18}$ to $5 \times 10^{22} Hz$. These rays have a wavelength of $6 \times 10^{-13}$ to $10^{-10} m$. Gamma rays are produced in nuclear reactions and are also emitted by radioactive nuclei.
