Question

WHEN YELLOW LIGHT AND BLUE LIGHT ARE INCIDENT ON THE BOUNDARY WITH SAME ANGLE OF INCIDENCE THEN.
a)there angle of refraction are equal
b)change in there speed will it same
c)bath a and b
d)neither a and b

Answer 1

Explanation:Snell's law critical angle

The critical angle can be found from Snell's law, putting in an angle of 90° for the angle of the refracted ray.
