Question

1.
Raman placed both a convex and a concave mirror
of radii 10 cm facing each other and 15 cm apart.
He placed a pin midway between them. Then, he
observes that the position of final image, if the
reflection first occurs at concave mirror and then in
convex mirror is​

Answer 1

Answer:

convex mirror and a concave mirror of radius 10 cm each are placed 15 cm apart facing each other. An object is placed midway between them. If the reflection ...
