A beam of light shining from water to air strikes the surface at an angle greater than 48° and produces total internal reflection. If the incident beam is at a 50° angle, at what angle is the reflected beam?

Question

anonymous · Answer

do u know about the laws of reflection?

cail · Answer

It is important to remember that the angle of incidence is always equal to the angle of reflection. Therefore the reflected beam would be at an angle of 50 as well... the incident angle is equal to the reflection angle 
i = r ---> i = 50 and then r = 50 degrees
