Find the focal length of a convex mirror whose radius of curvature is 60 cm
Answers
Answer:
We have
-Radius of curvature,
R = 60cm
Radius of curvature = 2 x Focal length (f)
=> R = 2f
=> f = R/2
=> f = 60/2
=> f = 30cm
Hence-
The focal length of the given convex mirror is 30cm.
Given, Radius of curvature R = 60cm
Radius of curvature = 2 x Focal length (f)
=> R = 2f
=> f = R/2
=> f = 60/2
=> f = 30cm
Hence, the focal length of the given convex mirror is 30cm.
The focal length of a spherical mirror is given by f=R2, where R is the mirror's radius of curvature.
A convex mirror's focus It is a point on the principal axis where incident light rays parallel to the principal axis appear to arrive after reflection from the mirror.
The focal length of a convex mirror is the distance between the focus and the convex mirror's pole.
