The energy of a photon 'E' is proportional to:
Correct answer: D. Frequency (f)
- A. The magnetic field (H)
- B. The electric field (E)
- C. Both the electric and magnetic fields Hand (E)
- D. Frequency (f)
Explanation
The energy of a photon is directly proportional to its frequency, as described by Planck's formula E = hf, where h is Planck's constant. This relationship is a fundamental principle in quantum mechanics. The other options, such as the magnetic field H, electric field E, and both electric and magnetic fields, are not directly related to the energy of a photon.

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.
