Total internal reflection can be understood in terms of refraction described by Snell's Law. Which one or more of the following statements about total internal reflection are true? (check all that are true) O The totally internally reflected ray obeys the Law of Reflection. For incident angles larger than the critical angle, the refracted ray bends further away from the normal. It is only possible when light travels from a higher refractive index to a lower one. The critical angle is the condition where the refracted ray makes an angle of 90 to the normal. O The critical angle only depends on the higher refractive index material. O It occurs when the incident angle is less than the critical angle. Question 2 1 pts A ray of light is incident on a plane mirror, making an angle 0 with the normal to the surface. The Law of Reflection says that the reflected ray will have an angle to the the normal, O, given by which of the following? O n2 cos(0') = n cos(0) O 8 = 20 O sin(0) = sin(90 - 0) %3D
