Question 26 • 26-27 LISD TX-Physics B-CR (rev. 5/25)

Which best compares convex and concave mirrors?

Answer

A

Convex mirrors produce only real images, and concave mirrors produce real and virtual images.

B

Convex mirrors produce only virtual images, and concave mirrors produce real and virtual images.

C

Concave mirrors produce only real images, and convex mirrors produce real and virtual images.

D

Concave mirrors produce only virtual images, and convex mirrors produce real and virtual images.

Explanation

A convex mirror always forms a virtual image because reflected rays spread apart and only appear to come from behind the mirror. A concave mirror can form a real image when the object is beyond its focal point, or a virtual image when the object is between the focal point and the mirror. Therefore, choice B is correct.
