Question

Define
a. Incident ray
b. Reflected ray
c. Normal
d. Angle of incidence
e. Angel of reflection
Explain law of reflection? with picture.

​

Answer 1

(pic 1)

Incident ray - Light whrich falls on the moreox | Dulished Surface is called incident g

Reflected ray - Ray of light which goes back in the same medium after striking the surface is called reflected day

Normal - The perpendicular drow to the reflecting surface is called normal at that point.

Angle of Incidence - The angle between the normal and incidence day is called of incidence

Angel of Reflection - The angle between the normal and reflected ray is called angle

LAW OF REFLECTION

1. The incident may, the reflected, the normal (at the point of incidence) all lie in the same plane.
2. The angle of reflection is always equal to the angle of incidence (pic 2)

$< i = < r$

• If the angle of incidence is to then the angle of reflection will also be 40°

• If the angle of incidence is to then the angle of reflection will also be 40°Remember that these angle are always measured from the normal not from the mirror

(pic 3)

Answer 2

Answer:

a Ray of light falling on the separating two medium is the incident ray

b a Ray of light travelling in another medium which change in the direction is the reflected ray

c. a ray that is incident at 90 degree to a surface is call normal Ray

d. the angle which is the incident ray Max with the normal is called angle of incident

e. the angle between a reflected ray and the normal drawn at the point of incident to reflected surface

the angle of reflection is always equal to angle of incident is called law of reflection
