Q: What is the relationship between the angle of incidence and the angle of reflection in total internal reflection?
Solution: In total internal reflection, the angle of incidence is equal to the angle of reflection.
Steps: 5
Step 1: Understand what total internal reflection is. It happens when light hits a boundary between two different materials and reflects back completely instead of passing through.
Step 2: Identify the angle of incidence. This is the angle between the incoming light ray and the normal line (an imaginary line perpendicular to the surface).
Step 3: Identify the angle of reflection. This is the angle between the reflected light ray and the normal line.
Step 4: Learn the key rule: In total internal reflection, the angle of incidence is always equal to the angle of reflection.
Step 5: Remember that this rule applies only in the case of total internal reflection, which occurs when light travels from a denser medium to a less dense medium.
