The refracting angle of prism is A and refractive index of material of prism is $\cot \frac{A}{2}$ The angle of minimum deviation is

Two thin biconvex lenses have focal lengths $f _{1}$ and $f _{2} .$ A third thin biconcave lens has focal length of $f_{3} .$ If the two biconvex lenses are in contact, the total power of the lenses is $P _{1}$. If the first convex lens is in contact with the third lens, the total power is $P _{2}$. If the second lens is in contact with the third lens, the total power is $P _{3}$ then

In refraction, light waves are bent on passing from one medium to second medium because, in the second medium.

If the refractive index from air to glass is $\frac{3}{2}$ and that from air to water is $\frac{4}{3}$, then the ratio of focal lengths of a glass lens in water and in air is

The following figure shows a beam of light converging at point \(P\). When a concave lens of focal length \(16 \,cm\) is introduced in the path of the beam at a place shown by dotted line such that \(OP\) becomes the axis of the lens, the beam converges at a distance \(x\) from the lens. The value of \(x\) will be equal to

A convex lens made of glass has focal length $0.15\, m$ in air. If the refractive index of glass is $3/2$, and that of water is $4/3$ the focal length of lens when immersed in water is

Colour of light having maximum speed in air is
