Light bends when it passes from onemedium to another due to a change in speed.

The angle of incidence is alwaysequal to the angle of refraction

A rainbow is an example of light dispersion

Diffraction is the bending of lightwaves around obstacles or through small openings

Light cannot be diffracted; only sound waves can.

Interference can only happen with sound waves, not with light waves

The colorful patterns seen on soap bubbles are due to light interference

Interference occurs when two or more light waves overlap and combine

Photoelectric effect is a nature of light as wave.

Refraction isa nature of light as wave.
