Question

Give the formula for the focal length of a convex mirror. Give any two uses of the convex mirror.

Hint:

Convex mirrors have a wide field of view and form virtual, diminished images.

Answer 1

The formula for the focal length \(f\) of a convex mirror is: \[ f = \frac{R}{2} \] where \(R\) is the radius of curvature of the mirror.
The uses of a convex mirror are: 1. Convex mirrors are used in vehicles as rearview mirrors because they provide a wider field of view. 2. They are used in security systems to monitor large areas.
