The energy of a photon is represented by:
Correct answer: C. h/f
- A. hf/c2
- B. hc2
- C. h/f
- D. h/c2
Explanation
The energy of a photon is given by the equation E = hf, where E is the energy, h is Planck's constant, and f is the frequency of the photon. Therefore, the correct representation of the energy of a photon is h/f.Option A incorrectly squares the speed of light in the denominator. Option B squares the speed of light but misses the frequency term. Option D also squares the speed of light and doesn't include the frequency term. These options do not accurately represent 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.
