Solution

The correct option is A $10^{22}$
Let n photon is required.

$E = n h v; n = \frac{331.5}{(6.6 \times 10^{- 34} \times 5 \times 10^{13})} = 10^{22}$

Hence, the correct option is $A$

Find the number of photons of radiation of frequency $5 \times 10^{13} s^{- 1}$ that must be absorbed in order to melt one gm ice when the latent heat of fusion of ice is 331.5j/g.

The correct option is A $10^{22}$
Let n photon is required.

$E = n h v; n = \frac{331.5}{(6.6 \times 10^{- 34} \times 5 \times 10^{13})} = 10^{22}$

Hence, the correct option is $A$
