Step-by-step explanation:
Consider a concave mirror and a convex lens (refractive index = 1.5) of focal length 10 cm each, separated by a distance of 50 cm in air (refractive index = 1) as shown in the figure. An object is placed at a distance of 15 cm from the mirror. Its erect image formed by this combination has magnification M
1
. When the set-up is kept in a medium of refractive index 7/6, the magnification becomes M
2
. The magnitude | M1 |
| M2 |
