According to quantum theory, the energy of a photon is directly proportional to which property of light:
Correct answer: A. Frequency
- A. Frequency
- B. Intensity
- C. Amplitude
- D. None of these
Explanation
A is the correct answer. According to the equation E=hν, where E is the energy of a photon, h is Planck's constant, and ν is the frequency of the light, the energy of a photon is directly proportional to its frequency. As the frequency increases, the energy of the photon also increases.

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.
