✒ (b) F

Option (b) is the correct answer of your question.

• For concave mirrors, when the object is between C and F, the image will be beyond C and will be enlarged and inverted.
• For concave mirrors, when the object is between F and the mirror, the image will be behind the mirror and will be enlarged and upright.

✒ What is a concave mirror ?

• If a hollow sphere is cut into parts and the outer surface of the cut part is painted, then it becomes a mirror with its inner surface as the reflecting surface.
• This kind of mirror is known as a concave mirror. Light converges at a point when it strikes and reflects back from the reflecting surface of the concave mirror.
• Hence, it is also known as a converging mirror. When the concave mirror is placed very close to the object, a magnified and virtual image is obtained.

✒ Uses of concave mirror :-

• Concave mirrors are used in a number of applications.
• They form upright, enlarged images, and are therefore useful in makeup application or shaving.
• They are also used in flashlights and headlights because they project parallel beams of light, and in telescopes because they focus light to produce greatly enlarged images.
