Question

Assertion(A): Convex mirror is used as a rear-view mirror in vehicles
Reason(R): Convex mirror gives a virtual, erect and diminished image of the object and
provides a wide range of view to the driver
(a) Both A and R are truc and Ris the correct explanation of A
(b) Both A and Rare true but is not the correct explanation of A
(c) A is true but R is false.
(d) A is false but R is true,​

Answer 1

Answer:

(a) Both A and R are true and R is the correct explanation of A.

Explanation:

Convex mirror are used as rear view mirror in vehicles because the field view of a convex mirror is large and it forms a diminished image so that the vehicles coming from behind can be observed. So, A and R are correct, and R is the correct explanation of A.

I hope it's help you!

Answer 2

Assertion(A): Convex mirror is used as a rear-view mirror in vehicles

Reason(R): Convex mirror gives a virtual, erect and diminished image of the object and

provides a wide range of view to the driver

• Both A and and R are true and R is the correct explanation of A.

But how ?

Convex mirrors are diverging mirrors which are able to produce only virtual images.

• Now, irrespective of the position of the object, convex mirrors always produce a a virtual, erect image smaller than the object.

• That means the driver will be able to visualise the car behind him to be smaller and erect which will help him to visualise a greater field of view.

• That is the main reason why convex mirrors are used as rear view mirrors in vehicles.

• See the ray diagram for better understanding.
