Answer 2

Correct answer choice is :

D) Diffraction

Step-by-step explanation:

Diffraction relates to several aspects that happen when a wave meets a barrier or a slit. It is described as the bending of waves around the edges of a barrier or gap into the area of the geometrical darkness of the barrier. Diffraction is created by one wave of light being turned by a diffracting thing. This shift will make the wave to have a collision with itself. The powerful examples of diffraction happen in waves where the wavelength is close to the mass of the object creating diffraction.
