A) The beam of red light would undergo total internal reflection.
B) The beam of red light would bend towards normal while it gets refracted through the second medium.
C) The beam of blue light would undergo total internal reflection.
D) The beam of green light would bend away from the normal as it gets refracted through the second medium.
Correct Answer: C
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.You need to login to perform this action.
