refraction
diffraction
interference
photoelectric effect

1 answer

The phenomena that support only the wave theory of light are:

  1. Diffraction
  2. Interference

Both diffraction and interference are behaviors exhibited by waves and cannot be adequately explained by particle theory alone. The photoelectric effect, on the other hand, supports the particle theory of light, indicating that light can also behave as particles (photons). Reflection and refraction can be explained by both wave and particle theories.
