In solar cooker, we use concave mirrors.

State two uses of a concave mirror.

Focal length of a concave mirror is

To construct a ray diagram, we use two rays which are so chosen that it is easy to know their directions after reflection from the mirror. List two such rays and state the path of these rays after reflection in case of concave mirrors. Use these two rays and draw ray diagram to locate the image of an object placed between pole and focus of a concave mirror.

A concave mirror of focal length 10cm is placed in front of a convex mirror of focal length 20 cm. The distance between the two mirrors is 20cm. A point object is placed 5cm from the concave mirror. Discuss the formation of image.

A convex lens (of focal length 20 cm) and a concave mirror, having their principal axes along the same lines , are Kept 80cm is to from eath other . The concave mirror is to the right of the convex lens. When an object is Kept at a distance of 30 cm to the left of the convex lens,its image remains at the same position even if the concave mirror is removed . The maximum distance of the object for which the concave mirror , by itself would produce a virtual would be:

STATEMENT- 1 For observing traffic at our back, we prefers to use a convex mirror STATEMENT 2 A convex mirror has a more larger field of view than a plane mirror or concave mirror.

The image formed by a concave mirror

A concave mirror and a convex mirror of focal lengths 10cm and 15cm are places at a distance of 70cm. An object AB of height 2cm is places at a distance of 30cm from the concave mirror. First ray is incident on the concave mirror then on the convex mirror. Find size, position, and nature of the image.

An object is placed in front of a concave mirror between the pole and the focus of the mirror. What is the nature of the image formed by the mirror ?

How will you distinguish between a plane mirror, a concave mirror and a convex mirror, without touching them?
