FOR A SPHERICAL MIRROR ____ IS TRUE.
|
|
f = 2R
|
|
|
R = 2f
|
|
|
fR = 1/2
|
|
|
fR = 2
|
Explanation:
Detailed explanation-1: -Explanation: For a spherical mirror, fR=2 is true.
Detailed explanation-2: -The relation between focal length (f) and radius of curvature (R) of a spherical mirror is that the focal length is equal to half of the radius of curvature i.e. f=R2.
Detailed explanation-3: -Radius of curvature is the radius of the spherical surface at which the mirror is a part. Focal length (f) : the distance between the pole and principal focus. option(c), for both convex and concave mirror.
