You are given four sources of light each one providing a light of a single colour – red, blue, green and yellow. Suppose the angle of refraction for a beam of yellow light corresponding to a particular angle of incidence at the interface of two media is $90^{circ}$. Which of the following statements is correct, if the source of yellow light is replaced with that of other lights without changing the angle of incidence?

Solution:

Here, for yellow light, $r = 90^{circ}$ when $i = C$.

As $i$ is kept same, $C$ must be smaller for total internal reflection.

From $mu =frac{1}{sin,C} , C$ will be smallest for blue colour. Therefore, blue light would undergo total internal reflection.
