dual-nature-of-radiation-and-matter Question 8

Question: Q. 8. Monochromatic light of frequency $6.0 \times 10^{14} \mathrm{~Hz}$ is produced by a laser. What is the energy of a photon in the light beam?

R [SQP 2018-19]

$$ \begin{align*} & \text {

Show Answer

Solution:

Ans. Each photon has an energy, } E=h v \ & \quad=\left(6.63 \times 10^{-34} \mathrm{~J}-\mathrm{s}\right)\left(6.0 \times 10^{14} \mathrm{~Hz}\right) \ & \quad=3.98 \times 10^{-19} \mathrm{~J} \end{align*} $$
