A light ray is incident from a denser medium on the boundary separating it from a rarer medium at an angle of incidence equal to the critical angle. What is the angle of refraction for the ray?
Best Answer
When a ray is incident from a denser medium to a rarer medium at angle equal to critical angle (a.PNG)
), the angle of refraction becomes 90°.
