Measurement Of Refractive Index Of Liquid By A Concave Mirror

Measurement Of Refractive Index Of A Liquid By A Travelling Microscope

Focal length of a convex lens of refraction Index 1.5 Is 2 cm. The focal length of lens when immersed in a liquid of refractive index of 1.25 will be.

The effective focal length of the lens combination shown in Fig. is -60 cm . The radii of curvature of the curved surfaces of the plano-convex lenses are 12 cm each and refractive index of the material of the lens is 1.5 . The refractive index of the liquid is : .

Assertion : A convex lens made of material of refractive index 1.2 behaves as diverging lens when kept in water of refractive index 4//3 . Reason : A convex lens made of material of refractive index 1.2 behaves as converging lens when placed in air.

Focal length of a convex lens of refractive index 1.5 is 2 cm. Focal length of lens when immersed in a liquid of refractive index 1.25 will be
