Question

define the following :- i Diffused Reflection and ii Angle of incidence .​

Answer 1

Answer:

1. Diffuse reflection is the reflection of light from a surface such that an incident ray is reflected at many angles, rather than at just one angle as in the case of specular reflection. ... Many common materials exhibit a mixture of specular and diffuse reflection.
2. , the angle of incidence is the angle between a ray incident on a surface and the line perpendicular to the surface at the point of incidence, called the normal. The ray can be formed by any wave: optical, acoustic, microwave, X-ray and so on

Explanation:

Answer 2

Answer:

Diffused reflection: A phenomenon that results when light strikes an irregular surface such as a frosted window or the surface of a frosted or coated light bulb.

Angle of incidence: when a ray of light and a perpendicular line meet at a surface they create the vertex of an angle. The distance of the angle between the ray of light and the perpendicular line is called the angle of incidence.
