Question

Increase in intensity of the light implies -

• A. increase in energy of photon.
• B. increase in number of photons crossing the given area per second.
• C. Both options $\left(A\right)$ and $\left(B\right)$
• D. None of these

Answer 1

The correct option is B increase in number of photons crossing the given area per second.

If the intensity of the light is increased, the number of photons crossing the given area per second increases, while the energy of each of the photons remains the same.

​​​​​​​Hence, option $\left(B\right)$ is the correct answer.
