Question

23. Explain regular and irregular reflection using a suitable ray diagram.​

Answer 1

Answer:

REGULAR REFLECTION - It is the reflection from a regular or plane surface.The rays are parallel after the reflection.

IRREGULAR REFLECTION - It is the reflection from a plane surface . The rays are not parallel after reflection.

Answer 2

Reflection is the bouncing back of light when light falls on a body such as silver, mirror etc.

There are two laws of reflection :

• The angle of incidence will be always equal to the angle of reflection.
• All the rays like the incident ray, reflected Ray and the normal will always lie on the same plane.

There are two types of reflection :

• Regular reflection
• Irregular reflection

Regular reflection: In regular reflection the light rays are reflected uniformly when falls on a polished or regular surface area. Such as light reflected from mirror is considered to be regular reflection.

Irregular reflection: In irregular reflection the light rays get dispersed when falls on a rough surface and the light rays get reflected non-uniformly. Such as light reflected from cement surface is considered to be irregular reflection.
