Answer 1

Answer:

Rear view mirror is convex mirror.

And therefore, option b) convex mirror is the correct answer.

Explanation:

Spherical mirrors are of two types :

• Concave mirror and

• Convex mirror.

• A concave mirror is made by silvering the outer surface.

• A convex mirror is made by silvering the inner surface.

• The Light rays incident on it diverge after reflection.

• The image formed by a convex mirror is always diminished for all people positions of the object in front of it.

Answer 2

≛ANSWER:-

✴Convex mirror is used as rear view mirror.

≛EXPLANATION:-

⚝The convex mirrors enable the driver to view much target oreo thon o plane mirror. The images produced ore erect ond their size is much smaller than the object. Hence, it is used as a rear view mirror in automobiles to see objects ot the backside of the vehicle.

WHY CONVEX MIRROR IS USED AS RARE VIEW MIRROR?

➊ Angle of incidence is equal to angle of reflection.

➋ The incident ray, the normal drawn to the mirror at the point of incident and the reflected ray all lie on the same plane.
