Question

define types of reflection​

Answer 1

Answer:

The reflection of light can be roughly categorized into two types of reflection. Specular reflection is defined as light reflected from a smooth surface at a definite angle, whereas diffuse reflection is produced by rough surfaces that tend to reflect light in all directions (as illustrated in Figure 3).

Answer 2

$\:\:\: \huge{\underline{\boxed{\sf{(a) Regular \: reflection - \: }}}}$

• When a beam of light falls on a smooth surface, the rays of the beam are reflected in a particular direction and remain parallel to each other. This is known as regular reflection.

• In regular reflection : Angle i = Angle r

• Images are formed by the regular reflection only.

$\:\:\: \huge{\underline{\boxed{\sf{(b) Diffused \: reflection - \: }}}}$

• When a beam of light falls on a rough surface, the rays of light are reflected in different direction and are not parallel to each other.

• In diffused reflection : Angle i = Angle r

• Light reaches to different corners of the room due to diffused reflection only.
