Q9.5Multiple choice
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°. 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?
- (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.
