Question

Total internal reflection takes place if the light ray strikes the interface at an angle with what relationship to the critical angle? Group of answer choices less than greater than equal zero

Answer 1

Answer:

In general, total internal reflection takes place at the boundary between two transparent media when a ray of light in a medium of higher index of refraction approaches the other medium at an angle of incidence greater than the critical angle. For a water-air surface the critical angle is 48.5°.................................
