In this lesson, we will learn how to define total internal reflection (TIR) by describing rays produced by light rays incident at or past the critical angle for TIR.
are shown incident on a boundary between water and air, traveling in water. Which incident ray produces total internal reflection?
Which of the following definitions best describes the critical angle for total internal
Which of the following sets of conditions best describes
total internal reflection?
A light ray travels along an optical fiber by total internal reflection, as shown in the
diagram. What is the most correct description for what happens at point
if light is sent
into the fiber when the fiber is bent?
Which of the following most correctly describes what happens if a light ray traveling in
water contacts a boundary between air and water at an angle greater than the critical angle
for a water–air interface?
