Q16 of 112 Page 310

Which type of reflection of light, regular reflection or diffuse reflection, leads to the formation of images?

Regular reflection, wherein the reflected rays are parallel to each other, lead to the formation of images because all the rays get reflected in a particular direction. Regular reflection always occurs from a smooth surface.
Diffused reflection does not lead to the formation of images because the rays do not reflect in one particular direction.
