Is sunlight a white light?

Why is white light white?

Is white light a composite light?

A composite light containing yellow, blue and orange colours is passed through a prism. Which colour bends the most?

When a composite light wave passes through a medium other than vacuum the speed of?

When a ray of composite light passes through a prism?

What is the composition of white light?

What is composite light?

Refractive index of a transparent material is

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. What is the dispersive power of the material of the lens ? (Round off your answer upto two decimal places)

What do you understand by the dispersion of light?

Find angular dispersion due to glass prism of refracting angle  $6°$. Refractive index for red and violet light is given as $1.514$ and $1.523$ respectively. 

Assertion: There is no dispersion of light refracted through a rectangular glass slab.

Reason: Dispersion of light is the phenomenon of splitting of a beam of white light into its constituent colours.

When light passes through a prism, the colour which deviates the least is :

By which optical phenomenon, the splitting of white light into seven constituent colours occur?

The respective angles of the flint and crown glass prisms are $A^{\text{'}}$ and $A$. They are to be used for dispersion without deviation, then the ratio of their angles $\frac{A^{\text{'}}}{A}$ will be,

The respective angle of the flint and crown glass prisms are A' and A. They are to be used for dispersion without deviation, then the ratio of their angles A'/A will be

When light is passed through a prism, the colour which deviates least is
