Question:

The following experiment suggests that light propagates as waves

Options:

Focault's method of finding the velocity of light in water

Einstein photoelectric emission experiment

Young's Double slit experiment

Compton's experiment on scattering of light

Correct Answer:

Young's Double slit experiment

Explanation:

The correct answer is Option (3) → Young's Double slit experiment

Young's Double Slit Experiment shows an interference pattern, which occurs only when light behaves as a wave and the amplitudes superpose. This is a clear signature of wave nature.

In contrast:

  • Foucault’s method determines speed, not nature.
  • Photoelectric effect shows particle nature.
  • Compton effect supports particle behavior (photon momentum).
