The graph between the frequency of incident light and the stopping potential is a:
Correct answer: B. Straight line
- A. Parabola
- B. Straight line
- C. Hyperbola
- D. Circle
Explanation
Stopping potential Vs which is linearly proportional to the frequency above the threshold. So the graph is a straight line.

About Dawn of Modern Physics
Classical physics cannot explain blackbody radiation and related observations, leading to Planck’s quantum theory, in which energy is emitted or absorbed in discrete packets. Photons provide the particle model of light, with energy and momentum linked to frequency and wavelength, including the photoelectric effect and its threshold frequency.

A metallic surface ejects photoelectrons when hit by green light but none when hit by yellow light. Will electrons be ejected if the same surface is hit by red light?
The human eye can barely detect yellow light (6000 Å) that delivers 1.7 × 10⁻¹⁸ watt to the retina. Nearly how many photons per second does the retina receive?
A modern 200-watt sodium street lamp emits yellow light of wavelength 0.6 µm. Assuming it is 25% efficient in converting electrical energy to light, the number of photons emitted per second is:
Light of frequency 1.5 times the threshold frequency is incident on a photosensitive material. If the frequency is halved and intensity doubled, the photoelectric current becomes:
What is the force exerted by a photon of intensity 1.4 kW/m² if it falls on a perfect absorber of radius 2 meters?
The rest mass of a photon is:
