Class 12PhysicsDual Nature of Radiation and matterPhotoelectric Effect by Lenard and it's Observations
EasyThe electrons are emitted in the photoelectric effect from a metal surface:
- AOnly if the frequency of the incident radiation is above a certain threshold value
- BOnly if the temperature of the surface is high
- CAt a rate that is independent of the nature of the metal
- DWith a maximum velocity proportional to the frequency of the incident radiation
