MCQ
The Einstein’s photo-electric equation is based upon the conservation of:
- AMass
- BMomentum
- CAngular momentum
- DEnergy
✓
Answer
- Energy
Explanation:
Einsteins photoelectric equations states that
Ek = hν − $\phi$
where, Ek 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.
