Question

A spherical mirror and a thin spherical lens have each a focal length of -15. The mirror and the lens are likely to be
1-BOTH concave
2-BOTH convex
3-THE mirror is concave and the lens is convex.
4-the mirror is convex and the lens is concave. ​

Answer 1

Answer:

BOTH CONVEX

BECAUSE THEY HAVE FOCAL LENGTH BEHIND THE MIRROR OR LENCE

Answer 2

The mirror and the lens are likely to be BOTH concave.

Explanation: By splitting up a hollow sphere, painting the external surface, and using the internal surface as the reflecting surface, a mirror can be created. Concave mirrors are these kinds of mirrors.

A concave lens bends a straight light beam away from the source and concentrates it into an upside-down, deformed virtual image.

Conventionally, the focal length of a concave mirror and a concave lens is assumed to be negative. As a result, the narrow spherical lens and the spherical mirror are both concave in shape.
