QNEET-2022-Ph-548: NEET 2022 Physics - Class 12 NEET-2022-Ph-548 Solution: The threshold frequency of a photoelectric metal is \( _0\). If …
The threshold frequency of a photoelectric metal is . If light of frequency is incident on this metal then the maximum kinetic energy of emitted electrons will be:
Multiple Choice Options
- A 4 hv 0
- B hv 0
- C 2 hv 0
- D 3 hv 0
Step-by-Step Verified Solution
According to Einstein's photoelectric equation
( K . E ) max = h v _ h v 0
( K . E ) max = h ( 4 v 0 ) _ h v 0
( K . E ) max = 3 h v 0
