In photo-electric effect, the energy of ejected electrons depend on:
Correct answer: B. The frequency of light
- A. The intensity of light
- B. The frequency of light
- C. Both intensity and frequency
- D. amplitude of the above
Explanation
In the photo-electric effect, the energy of ejected electrons depends on the frequency of light. This is because the energy of photons is directly proportional to their frequency, and it is this energy that is transferred to the electrons during the photo-electric effect. The other options are incorrect because they do not accurately reflect the key factor influencing the energy of ejected electrons in this phenomenon.

About Optics
Light is studied through reflection, refraction, dispersion, interference, diffraction and polarization, linking ray behavior with its wave nature. Questions may involve mirrors, lenses, optical instruments, refractive index and image formation, while geometrical optics deals with rays and wave optics explains effects such as interference and diffraction.
