1.
$A$ and $B$ are two metals with threshold frequencies $1.8 \times 10^{14}\, Hz$ and $2.2 \times 10^{4}\, Hz$ Two identical photons of energy $0.825 \,eV$ each are incident on them. Then photoelectrons are emitted by (Take $\left.h=6.6 \times 10^{-34} \,J - s \right)$- B alone
- A alone
- Neither A nor B
- Both A and B
2.
Hologram is based on phenomenon of- diffraction
- polarisation
- interference
- total internal reflection
3.
The collector plate in an experiment on photoelectric effect is kept vertically above the emitter plate. Light source is put on and a saturation photo-current is recorded. An electric field is switched on which has a vertically downward direction, then- the photo-current will increase
- the kinetic energy of the electrons will increase
- the stopping potential will decrease
- the threshold wavelength will increase
4.
In photoelectric emission process from a metal of work function $1.8 \,eV,$ the kinetic energy of most energetic electrons is $0.5 \,eV$. The corresponding stopping potential is- 1.3V
- 0.5V
- 2.3V
- 1.8V
