Question
Different colors of light have different critical angles for total internal reflection. Is the critical angle greater for colors of light that travel faster or slower in the medium? Explain.
Step 1
The refractive index (n) of a medium is the ratio of the speed of light in vacuum (c) to the speed of light in the medium (v). It is given by the formula: \[ n = \frac{c}{v} \] Show more…

During refraction, will a smaller or larger angle of incidence produce more color dispersion? Why?
Triple Choice Is the critical angle for total internal reflection of red light passing from glass into air greater than, less than, or equal to the critical angle for blue light? Explain.
Total internal reflection is the phenomenon of reflection of light into denser medium at the interface of denser medium with a rarer medium. Light must. travel from denser to rarer and angle incidence denser medium must be greater than critical angle (C) for the pair of media in contact. We can show that $$ \mu=\frac{1}{\sin C} $$ Critical angle for air water interface for violet colour is $49^{\circ}$. Its value for red colour would be (a) $49^{\circ}$ (b) $50^{\circ}$ (c) $48^{*}$ (d) cannot say
