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» Hey 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!

Hey 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!
