Light of wavelength lambda shines on a m...

Light of wavelength `lambda` shines on a metal surface with initail X and the metal emit Y electron per second of average Z what will happen to Y and Z if X is doubled ?

A

Z will remains constant and Y will increase

B

Both Z and Y will remain constant

C

Z will decrease and Y will increase

D

Both Z and Y will increase

Text Solution

Verified by Experts

The correct Answer is:
A
If intensity of incident light is doubled, there will not be any change in the energy (Z) of photoelectrons ejected but the number of photoelectrons ejected (Y) will increase.
