Answer 1

Question 1.

The energy of a photon of light is inversely proportional to its wavelength and directly proportional to its frequency. (i.e. Option C)

Explanation: The energy of light (E) can be expressed as follows.

E = h $\nu$ , where h is the Planck's constant and $\nu$ is the frequency of light.

Hence, the energy of a photon is directly proportional to its frequency.

Now, c = $\nu$ $\lambda$ , i.e. $\nu$ = c/ $\lambda$ , where c is the velocity of light and $\lambda$ is its wavelength.

Therefore, E = hc/ $\lambda$

Hence, the energy of a photon is inversely proportional to its wavelength.
