Assertion The formula connecting u, v and f for a spherical mirror is valid only for mirrors sizes which are very small compared to their radii of curvature.
Reason Laws of reflection are stricity valid for plane surface, but not for large spherical.

A

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

B

Both A and R are true but R is NOT the correct explanation of A

C

A is true but R is false

D

A is false and R is True

Text Solution

Verified by Experts

The correct Answer is:
C
The mirror formula is derived under the consideration that the incident rays are paraxial which means that the rays lie very close to the principal axis. Hence the mirror aperture is considered to be small. So, the assertion is true.
Laws of reflection is valid for any surface plane or spherical. Hence the reason is false.

In each of the questions, assertion(A) is given by corresponding statement of reason (R) of the statemens. Mark the correct answer. Q. Statement I: The formula connecting u,v and f for a spherical mirror is valid only for mirrors whose sizes are very small compared to their radii of curvature. Statement II: Laws of reflection are strictly valid for plane surfaces, but not for large spherical surfaces.

The formula connecting u,v and f for a spherical mirror is valid only for mirrors whose sizes are very small compared to their radii of curvature. Because Statement-2 Laws of reflection are strictly valid for plane surfaces, but nor for large spherical surfaces.s

Statement - 1 : The formula connecting u, v and f for a spherical mirror is valid only for mirrors whose sizes are very small compared to their radii of curvature. Because Statement - 2 : Laws of reflection are strictly valid for plane surfaces, but not for large spherical surfaces.

Assertion:- The formula ((1)/(4)+(1)/(u)=(1)/(f)) connecting u and v for a spherical mirror is valid only for mirros whose sizes are very small compared to their radii of curvatures. Reason:- Laws of reflection are strictly valid for smaller size of of optical system.

Assertion : Focal length of a spherical mirror does not depend on the material from which mirror is made but same for the lens depends on the material of lens. Reason : Law of reflection does not depend on material and surrounding medium but law of refraction depends on refractive index of the materials.
