1. (a) concave mirror, (b) plane mirror, (c) real image.
2. (a) plane mirror, (b) concave mirror, (c) real image.
3. (a)concave mirror, (b) real image, (c) plane mirror.
4. (a) plane mirror, (b) real image, (c) concave mirror.​

Answer 1

Given:

• Mirror having magnification always equal to one.
• Mirror used to concentrate sunlight in reflecting solar cooker.
• Image can be obtained on screen.

Solution:

• The mirror which has magnification equal to one is a PLANE MIRROR. This means that the object height is equal to image height (i.e. they are of same size).

• Solar cookers use CONCAVE MIRRORS to concentrate sunlight at the focus which generates lots of heat. This heat can be used for cooking.

• Images which can be protected on a screen is REAL IMAGE. Concave mirrors can produce real image only in certain cases. Whereas Plane mirrors and Convex mirrors always produce virtual image.

OPTION 2) IS CORRECT ✔️
