NEET PYQs for Images Formed By Lenses with Solutions

1.
In a certain camera, a combination of four similar thin convex lenses are arranged axially in contact. Then the power of the combination and the total magnification in comparison to one lens will be, respectively:
- $ 4p $ and $ m^4 $
- $ p $ and $ 4m $
- $ p $ and $ m^4 $
- $ 4p $ and $ 4m $

2.
A plano-convex lens fits exactly into a plano- concave lens. Their plane surfaces are parallel to each other. If lenses are made of different materials of refractive indices, $μ_1$ and $μ_2$ and R is the radius of curvature of the curved surface of the lenses, then the focal length of the combination is
- $\frac{R}{2(μ_1 +μ_2)}$
- $\frac{R}{2(μ_1 - μ_2)}$
- $\frac{R}{(μ_1 - μ_2)}$
- $\frac{2R}{(μ_2 - μ_1)}$

3.
Two similar thin equi-convex lenses, of focal length $f$ each, are kept coaxially in contact with each other such that the focal length of the combination is $F_1$. When the space between the two lenses is filled with glycerin (which has the same refractive index ($\mu=-1.5$) as that of glass) then the equivalent focal length is$ F_2.$ The ratio $F1: F2$ will be:
- $2:1$
- $1:2$
- $2:3$
- $3:4$
