Which of the following has a larger chromatic aberration?
 

What causes Chromatic aberration in lenses?

A ray of light passes through an equilateral prism such that angle of incidence is equal to angle of emergence and the latter is equal to ${\left(\frac{3}{4}\right)}^{\mathrm{t}\mathrm{h}}$ of the angle of prism. The angle of deviation is (in${}^{\circ }$) 

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. 

If the yellow light is refracted by a prism at an angle of minimum deviation then-

If the retractive index vs wave length for a thin prism be as shown in figure. Then the graph of angle of deviation $\left(\delta \right)$ vs $\lambda$ graph is best represented by

Calculate the dispersive power for crown glass from the given data

${\mu }_V=1.523$ and ${\mu }_R=1.5145$

Two identical thin isosceles prisms of refracting angle 'A' and refractive index m are placed with their bases touching each other. Two parallel rays of light are incident on this system as shown. The distance of the point where the rays converge from the prism is

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

Three thin prisms are combined as shown in diagram. The refractive indices of the crown glass for red and violet rays are ${\mu }_{\text{r}}$ and ${\mu }_{\text{v}}$ respectively and those for the flint glass are ${\mu }_{\text{r}}^{\prime }$ and ${\mu }_{\text{v}}^{\prime }$respectively. The ratio $\frac{{\text{A}}^{\prime }}{\text{A}}$ for which there is no net angular dispersion

A ray of light is incident at an angle of incidence i, on one face of a prism of angle A (assumed to be small) and emerges normally from the opposite face. If the refractive index of the prism is μ, the angle of incidence i, is nearly equal to
