An object is placed 15cm from a mirror and an image is captured on the screen with magnification 2. Calculate the focal length of the mirror and determing if it is concave or convex.

For an object placed at a distance 20 cm from a concave mirror, the image is formed at the same position. What is the focal length of the mirror?

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 ?

An object is places 15 cm from a mirror and an erect image of size 5cm is seen. Determing the focal length and the nature of the mirror. Assume the object size is 15 cm.
