Pick the wrong answer in the context with rainbow.
A drop of liquid is spread on the hypotenuse of $$30^o -60^o -90^o$$ prism as shown and a ray of light incident normally on face $$AB$$ of the prism. If the refractive index of liquid is $$1.3$$, then the refractive index of prism, so that total internal reflection take place is :

In total reflection when the angle of incidence is equal to the critical angle then angle of refraction is?
Consider the ray diagram for the refraction given below. The maximum value of angle 6 for which the light suffers total internal reflection at the vertical surface, is
Figure shows, a glass prism $$ABC$$ (refractive index $$1.5$$), immersed in water (refractive index $$4/3$$). A ray of light incident normally on face $$AB$$. If it is totally reflected at face $$AC$$ then :
Which of the following graphs will represent the angle of deviation $$\delta$$ by a versus angle of incident $$i$$ for a monochromatic light ?
If a crown glass prism of refracting angle $$10^o$$ have refractive indies for red and violet rays $$1.514$$ and $$1.523$$ respectively, then the dispersion caused by a crown glass prism is :
Find the minimum and maximum deflection angles for a light ray passing through a glass prism with refracting angle $$ \theta=60^{\circ} $$
A trihedral prism with refracting angle $$ 60^{\circ} $$ provides the least deflection angle $$ 37^{\circ} $$ in air. Find the least deflection angle of that prism in water.
