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

A

Statement-`1` is True, Statement-`2` is True, Statement-`2` is a correct explanation for Statement -`1`

B

Statement-`1` is True, Statement-`2` is True, Statement-`2` is `NOT` a correct explanation for Statement -`1`

C

Statement-`1` is True, Statement-`2` is False

D

Statement-`1` is False, Statement-`2` is True.

Text Solution

Verified by Experts

The correct Answer is:
C

Laws of reflection are valid for all surfaces.
So statement `(2)` is incorrect.

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.

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.

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.

STATEMENT-1: In high-quality optical devices, such as camera, binocular, periscope, et.c prisms are used in place of plane mirrors to reflect light. STATEMENT-2: In plane mirrors, reflections occur both in the front and rear (silvered) surfaces.
