Answer 1

11.incident ray reflected ray nd the normal lie on the point of incidence at a plane surface

Answer 2

Ans 11:- The law of reflection states that the incident ray the reflected ray , and the normal to surface of the mirror all lie in the same plane .

Ans 12:- A spherical mirror is a mirror which has the shape of a piece cut out of a spherical surface .

Ans 13:- There are two types of spherical mirrors :-

1) Concave Mirror
2) Convex Mirror

Ans 14 :- A concave mirror is composed of a reflective surface with its sides curved closer in distance to your eye than its middle surface .

Ans 15 :- Pole is the mid point of a spherical mirror .

Ans 16 :- centre of curvature is the centre of the sphere of which the spherical mirror is a part .

Ans 17 :- Radius of curvature is the linear distance between the pole and the centre of curvature .
