Identify the correct statement(s) with respect to the reflection of light by a spherical mirror from among the following.

(A) A convex mirror can only form real and inverted images.

(B) A concave mirror can form real, inverted and virtual, erect images.

(C) Images formed by convex mirrors are either diminished, same size or enlarged depending on the position of object.

(D) Images formed by concave mirrors are either diminished, same size or enlarged

Correct option is A

​The correct answer is (a) (B) and (D) are only correct.

Options Explanation:

• (A) A convex mirror can only form real and inverted images.
• Incorrect. A convex mirror always forms virtual, erect, and diminished images, regardless of the position of the object. This is due to the diverging nature of light rays in convex mirrors. It does not form real or inverted images.
• (B) A concave mirror can form real, inverted and virtual, erect images.
• Correct. A concave mirror can form both real and virtual images, depending on the position of the object:
• If the object is outside the focal point, the image is real and inverted.
• If the object is inside the focal point, the image is virtual and erect.
• (C) Images formed by convex mirrors are either diminished, same size or enlarged depending on the position of the object.
• Incorrect. Images formed by convex mirrors are always diminished, virtual, and erect, regardless of the object's position. The size of the image never increases or stays the same.
• (D) Images formed by concave mirrors are either diminished, same size or enlarged.
• Correct. A concave mirror can form images that are:
• Diminished: When the object is beyond the focal point.
• Same size: When the object is at the focal point (very rare in practice).
• Enlarged: When the object is inside the focal point (between the mirror and the focal point).

Information Booster:

• Concave mirrors are used in automobiles and motor vehicles headlights, torchlights, railway engines, etc. as reflectors.
• Convex mirrors are used in magnification glasses, sunglasses, and rear view mirror in vehicles, ATMs, and street lights.
