Which of the following is not the property of the photons?
1 Momentum
2 Energy
3 Charge
4 Velocity
Explanation:
C The momentum of the photon is $\mathrm{h} / \mathrm{v}$ and its velocity is the velocity of light. So, the charge is not the property of photons.

Particle nature and wave nature of electromagnetic waves and electrons can be represented by:
1 photoelectricity and electron microscopy
2 light is refracted and diffracted
3 X-rays is diffracted, reflected by thick metal sheet
4 electrons have small mass, deflected by the metal sheet.
Explanation:
A Particle nature and wave nature of electromagnetic wave and electron can be represented by photo- electricity and electron microscopy. Photo electricity illustrates the particle nature of waves. A photon is a wave particle. Electron microscopy represents the wave behaviour of a particle.

When intensity of incident light increases
1 photocurrent increases
2 photocurrent decreases
3 kinetic energy of emitted photoelectric increases
4 kinetic energy of emitted photoelectrons decreases
Explanation:
A When intensity of incident light increase photo current increase because number of photons increases in incident light. If number of incident photons increases, then number of emitted photo electron also increases. Therefore the photo electric current increases.
