What is the work function? Why doesn't red light emit photons? What is stopping potential? How do you know when you have reached the stopping potential for a particular material?

Answer 1

Focal length is always equal to half the radius of curvature.

Photoelectric effect is the phenomenon of ejecting electrons from a metal surface after striking with a photon of suitable energy.

Work function of every metal is the minimum amount of energy required by the photon to eject electrons

Focal length is always equal to half the radius of curvature.

Photoelectric effect is the phenomenon of ejecting electrons from a metal surface after striking with a photon of suitable energy.

Work function of every metal is the minimum amount of energy required by the photon to eject electrons from that particular metal by photoelectric effect.

Stopping potential is the reverse potential applied to metal so that the ejected electrons are ejected with zero kinetic energy.

from that particular metal by photoelectric effect.

Stopping potential is the reverse potential applied to metal so that the ejected electrons are ejected with zero kinetic energy.

The photos current becomes zero when we reach stopping potential.
