MCQ

This question has Statement $1$ and Statement $2.$ Of the four choices given after the Statements, choose the one that best describes the two Statements.

Statement $1:$ A metallic surface is irradiated by a monochromatic light of frequency $v > v_0$ (the threshold frequency). If the incident frequency is now doubled, the photocurrent and the maximum kinetic energy are also doubled.

Statement $2:$ The maximum kinetic energy of photoelectrons emitted from a surface is linearly dependent on the frequency of the incident light. The photocurrent depends only on the intensity of the incident light.

A
Statement $1$ is true, Statement $2$ is true,

Statement $2$ is the correct explanation of Statement $1$
✓
Statement $1$ is false, Statement $2$ is true.
C
Statement $1$ is true, Statement $2$ is false.
D
Statement $1$ is true, Statement $2$ is true,

Statement $2$ is not the correct explanation of Statement $1.$

✓

Answer

Correct option: B.

Statement $1$ is false, Statement $2$ is true.

b
The maximum kinetic energy of photoelectrons depends upon frequency on incident light and photo current depends upon intensity of incident light.
