The graph between angle of deviation $(\delta)$ and angle of incidence $(i)$ for a triangular prism is represented by :-

The angle of prism is $5^o$ and its refractive indices for red and violet colours are $1.5$ and $1.6$ respectively. The angular dispersion produced by the prism is.....$^o$

Which colour has more speed in a glass prism? Blue or yellow?

$A$ yellow light undergoes minimum deviation through a prism. If $i_1$ and $i_2$ are the angle of incidence and the angle of emergence respectively,then:

$A$ ray of monochromatic light suffers a minimum deviation of $38^{\circ}$ while passing through a prism of refracting angle $60^{\circ}$. The refractive index of the prism material is:

In a thin prism of glass (refractive index $\mu = 1.5$),which of the following relations between the angle of minimum deviation $\delta_m$ and the angle of the prism $A$ (where $A = 2r$ for a thin prism) is correct?
