1.	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 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 M1.When the set up is kept in a medium of refractive index 76, the magnification becomes M2. The magnitude of ∣∣∣M2M1∣∣∣ is
Answer» 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 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 $\frac{7}{6}$ , the magnification becomes $M_{2}$ . The magnitude of $∣ ∣ ∣ \frac{M_{2}}{M_{1}} ∣ ∣ ∣$ is
