Question

Which phenomenon provides evidence that light

Answer 1

Answer:

(2) diffraction of light passing through a narrow  opening

Explanation:

As we know that when light passes through a small opening then the wavefront that passes  through small opening will behave like a combination of large number of point sources.

Each point source will emit a wave and due to superposition of all such waves we can observe a pattern of maximum and minimum on the screen.

this is given by the equation

$a sin\theta = N\lambda$

so here we can say that the correct answer will be

(2) diffraction of light passing through a narrow  opening

Answer 2

The diffraction f light passing through a narrow opening, provides evidence that light has a wave nature.
