The energy of a photon is directly proportional to
Correct answer: C. Frequency
- A. Wavelength
- B. Intensity
- C. Frequency
- D. None of these
Explanation
The energy of a photon is given by Planck's equation, E = hν, where E represents energy, h is Planck's constant, and ν (nu) is the frequency of the photon. This equation signifies a direct proportionality between energy and frequency. Thus, the correct answer is that photon's energy is directly proportional to its frequency. In contrast, wavelength is inversely related to frequency, as shown by the formula E = hc/λ. Intensity refers to the overall number of photons, not the energy of an individual photon, making it irrelevant to this relationship.

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.
