You are given four sources of light each one providing a light of 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^(@)` . Which of the following statement is correct if the source of yellow light is replaced with other lights without changing the angle of incidence?

A

The beam of red light would undergo total internal reflection

B

The beam of red light would bend towards the 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
