The _____ of a mirror determines the type of image it forms.

_____ mirrors from the perfect image of an object.

Name the two types of spherical mirrors.

In a Michelson experiment for measuring speed of light, the distance travelled by light between two reflections from the rotating mirror is 4.8 km. The rotating mirror has a shape of a regular octagon. At what minimum angular speed of the mirror (other than zero) the image is formed at the position where a non rotating mirror forms it ?

If an object is placed at the focus of a concave mirror, where is the. image formed?

Can a plane mirror ever form a real image ?

Two mirror are parallel to each other, then the number of images formed is _____.

A converging mirror M_1 a point source S and a diverging mirror M_2 are arranged as shown in figure. The source is placed at a distance of 30 cm from M_1 . The focal length of each of the mirrors is 20 cm. Consider only the images formed by a maximum of two reflections. It is found that one image is formed on the source itself. (a) Find the distance between the two mirrors. (b) Find the location of the image formed by the single reflection from M_2

Curved mirrors from the perfact image of an object.

A converging lens of focal length 15 cm and a converging mirror of focal length 10 cm are placed 50 cm apart. If a pin of length 2.0 cm is placed 30 cm from the lens farther away from the mirror, where will the final image form and what will be the size of the final image ?
