A

Velocity of emitted photoelectron decreases

B

Velocity of emitted photoelectron increases

C

Velocity of photoelectron do not change

D

Photo electric current increases

Verified by Experts

The correct Answer is:
B
`K_("max")=hc[1/lamda-1/lamda_0]`
As `lamda` decrease, `K_("max")` increases.
