Question

formula of aperture of mirrors?
​

Answer 1

Answer:

o Radius of curvature: The radius of curvature of the spherical mirror is the radius of the sphere of which the mirror forms a part. It is represented by R. Hence, PC = R. ... Angular aperture of a spherical mirror is the angle , subtended at centre of curvature C by the diameter of the spherical mirror.

Explanation: is it correct please mark me as ....................

Answer 2

Answer:

Mirror formula for concave mirror

Explanation:

Now, P is the pole, F is the principal focus and C is the centre of curvature of a concave mirror of small aperture. Suppose PF = f is the focal length and PC = R is the radius of curvature of the mirror.
