A metallic surface ejects electrons when hit by green light but none when hit by yellow light .
Will the electrons be ejected if the same surface is hit by red light

A

Yes

B

No

C

Yes, if the red bream is quite intense

D

Yes, if the red beam continues to fall upon

Text Solution

Verified by Experts

The correct Answer is:
B
Red light has less frequency than green. So, it will not cause ejection of electrons
