It is desired to make an achromatic combination of two lenses $(L_1 \& L_2)$ ${\omega }_1$ and ${\omega }_2 (<{\omega }_1)$. If the combination of lenses is converging then

In the dispersion of white light by a common glass prism, which one among the following is correct?

The refracting angle of a prism is $60°$. What should be the minimum value of the refractive index of the material from which the prism is to be made so that light cannot emerge from the second refracting surface?

I) The speed of light does not depend upon the nature of medium through which it passes.

II) The beam of light is deviated or refrected from its original path as it passes from one medium to another.

III) When a ray of light is passed through a prism, the wave with shorter wavelength bends more than one with longer wavelength.

Which of the following statements is true?

A parallel beam is incident on to a lens of focal length $f$ (positive), parallel to its principal axis. A thin prism of vertex angle $A$ and refractive index $\mu$ is inserted in the path of the parallel beam before it falls on the lens. The focal point of the image

Glass prism having a refractive index $\mu$, placed in a air, for that angle of minimum deviation of prism is same as angle of prism. Then what is value of angle of prism?

A mixture of red, yellow and violet light is incident on one face of a prism, at an angle of incidence of $50°$. The angle of emergence of the red beam from the other face is $58.56°$. If the angular dispersion of the emerging beam is $4.62°$, then

$I_1, I_2 and I_3$ rays sent to X,Y and Z prisms in the air medium follow the paths in the figures.

What is the relationship between the refractive indices ${\mu }_x,{\mu }_y and {\mu }_z$ of the X,Y and Z prisms?

A beam of light consisting of red, green and blue colours is incident on a right angled prism. The refractive indices of the material of the prism for the above red, green and blue wavelength are 1.39, 1.44, and 1.47 respectively. The prism will

A parallel beam of white light falls on a convex lens. Images of violet, yellow and orange light are formed on the other side of the lens at $t$ distances $24 \mathrm{cm},30 \mathrm{cm}$ and $32 \mathrm{cm}$ respectively.
