A 3.0 cm object is placed 8.0 cm in front of a mirror.The virtual image is 4.0 cm further from the mirror when the mirror is concave than when it is planar.
Determine the focal length of the concave mirror.

A 3.0 cm object is placed 8.0 cm in front of a mirror.The virtual image is 4.0 cm further from the mirror when the mirror is concave than when it is planar. Determine the image height in the concave mirror.

If an object is placed 10 cm infront of a concave mirror of focal length 20cm, the image will be

An object is placed at 15 cm in front of a concave mirror whose focal length is 10 cm. The image formed will be

An object is placed 18 cm in front of a mirror. If the image is formed at 4 cm to the right of the mirror, calculate its focal length. Is the mirror convex or concave ? What is the nature of the image ? What is the radius of curvature of the mirror ?
