A spherical mirror and a thin spherical lens each have a focal length

1.	A spherical mirror and a thin spherical lens each have a focal length of -15 cm.The mirror and lens are likely to be- 1 pointBoth concaveBoth convexMirror is concave, lens convexMirror is convex, lens concave
Answer» there! Amongst convex and concave mirrors according to sign convention we can say that a concave mirror has a NEGATIVE focal LENGTH similarly if check the sign convention for a concave lens the focal length of a concave lens is ALSO negative so your answer is both concave Hope it HELPS!

Amongst convex and concave mirrors according to sign convention we can say that a concave mirror has a NEGATIVE focal LENGTH

similarly if check the sign convention for a concave lens the focal length of a concave lens is ALSO negative

so your answer is both concave

Hope it HELPS!
