If a source of electromagnetic radiation having power $15 kW$ produces $10^{16}$ photons per second, the radiation belongs to a part of spectrum is.

(Take Planck constant $h = 6 \times 10^{- 34} Js$ )

Accepted Answer

\begin{aligned} Energy of one photon = \frac{Power}{Photon frequency} \\ E = h v = \frac{15 \times 10^{3}}{10^{16}} \\ \Rightarrow v = \frac{15 \times 10^{- 13}}{6 \times 10^{- 34}} = 2.5 \times 10^{21} \end{aligned}

So gamma Rays.
