MCQ
The Einstein’s photo$-$electric equation is based upon the conservation of:
- AMass
- BMomentum
- CAngular momentum
- ✓Energy
✓
Answer
Correct option: D.
Energy
Einsteins photoelectric equations states that
$E_k$ = hν − $\phi$
where, $E_k$ is maximum kinetic energy of emitted photoelectrons
$h$ is plank's constant.
$ν$ is frequency of incident light
$\phi$ is work function of metal.
So, it is clearly based upon energy conservation.
