For finding the focal length of a concave mirror, where do we keep the object? What is the position of image formed? On which structure we get the image? What is the nature of the image formed?

The focal length of a concave lens is 20 cm, if an object is placed at a distance of 50 cm in front of this concave lens, where is the image formed ? What is the nature of the image ?

The focal length of a concave mirror is 15 cm. if the object distance is 20 cm, find the Position and nature of the image.

When the image formed by a concave mirror is at infinity then what is the position of the object?

An object is kept on the principal axis of a concave mirror of focal length 12 cm. If the object is at a distance of 18 cm from the mirror, calculate the image distance. Determine the nature of the image formed by calculating the magnification produced by the mirror.

A concave mirror has a focal length of 10 cm. Where can we place the object so that the image formed is magnified to twice the size of object ?

We get a virtual image in a concave mirror when the object is placed…….
