Answer: The correct answer is Diffraction.
Explanation:
Diffraction is the phenomenon in which a beam of light will get bend when it passes through a narrow aperture. It is accompanied by the interference between the wave form produced.
Consider a wave approaching a barrier with a small hole. The diffraction will occur when the wave passes through the hole. There is a bending of light as it passes through the edge of the object or through the hole.
The amount of bending light depends on the relative size of wavelength of the light in comparison to the size of the aperture.
Therefore, the correct answer is Diffraction.
