Question

3. Explain the following terms :
(a) plane mirror,
(b) incident ray,
(c) reflected ray, (d) angle of incidence, and
(e) angle of reflection.
Explain all the rays​

Answer 1

Answer:

(a) Incident ray: The ray of light that falls on the mirror surface is called the incident ray.

(b) Point of Incidence: The point at which the incident ray falls on the mirror is called the point of incidence.

(c) Normal: The normal is a line at right angle to the mirror surface at the point of incidence.

(d) Reflected ray: The ray of light which is sent back by the mirror is called the reflected ray.

(e) Angle of incidence: The angle of incidence is the angle made by the incident ray with the normal at the point of incidence.

(f) Angle of reflection: The angle of reflection is the angle made by the reflected ray with the normal at the point of incidence.

Answer 2

Answer:

a)plane mirror:it is a mirror with flat reflective surface

b)incident Ray: the Ray which incidents is called incident Ray

c)reflected ray: the Ray which is reflected is called reflected ray

d) angle of incidence: an angle which is made by incidental Ray is angle of incidence ray

e) angle of refrection: an angle which is made by reflected Ray's is called angle of reflection
