A finite size object is placed normal to the principal axis at a distance of 30 cm from
a convex mirror of focal length 30 cm . A plane mirror is now placed in such a way that the image produced by both the mirrors coincide with each other. The distance between the two mirrors is:
Text Solution
Verified by ExpertsB
For Convex mirror
Image formed by convex mirror is at 45cm from
object so plane mirror should be placed midway at
22.5 cm from object so that both of their images
may coinside,
Therefore distance between both mirrors
= 30 – 22.5 = 7.5 cm
