Questions & Step-by-Step Solutions
In which of the following scenarios will total internal reflection occur?
Step 1: Understand what total internal reflection is. It happens when light hits the boundary between two different materials.
Step 2: Identify the two types of materials involved. One is a denser medium (like glass) and the other is a less dense medium (like air).
Step 3: Know that light must travel from the denser medium to the less dense medium for total internal reflection to occur.
Step 4: Check the angle of incidence. Total internal reflection only happens if the angle at which the light hits the boundary is greater than a specific angle called the critical angle.
Step 5: Remember that if the light is traveling from a less dense medium to a denser medium, total internal reflection will not occur.
