Dual nature of radiation and Matter
142284
Following process is known as $h v \leftrightarrow \mathrm{e}^{+}+\mathrm{e}^{-}$
1 Pair production
2 photoelectric effect
3 Compton effect
4 Zeeman effect
Explanation:
A The conversion of a photon into pairs of electron and positron, when it interacts with a strong electric field present around a nucleus is known as pair production. Thus, it explains the conversion of radiant energy to matter.

Dual nature of radiation and Matter
142322
Which of the following is true ?
1 The stopping potential increases with increasing intensity of incident light
2 The photocurrent increases with increasing intensity of light
3 The current in photocell increases with increasing frequency of light
4 The photocurrent is proportional to applied voltage
Explanation:
B The emission of photoelectron is directly proportional to the intensity of the incident light therefore photo current increases with the intensity of light.
