Question

Study the given ray diagrams and select the correct statement from the following:
(A) Device X is a concave mirror and device Y is a convex lens, whose focal lengths are 20 cm and 25 cm respectively.
(B) Device X is a convex lens and device Y is a concave mirror, whose focal lengths are 10 cm and 25 cm respectively.
(C) Device X is a concave lens and device Y is a convex mirror, whose focal lengths are 20 cm and 25 cm respectively.
(D) Device X is a convex lens and device Y is a concave mirror, whose focal lengths are 20 cm and 25 cm respectively

Answer 1

(A) Device X is a concave mirror and device Y is a convex lens, whose focal lengths are 20 cm and 25 cm respectively.

this is the right answer

because in the case of mirrors the concave mirrors converge the light rays at one point and it is given in the diagram that the focal length is 20cm.

plz mark as brainliest

byee!

Answer 2

Device X is concave lens and device y is concave mirror whose focal length are 20 and 25 CM respectively
