3 cards from this section. Quick, good the night before a test.
What is the critical angle when light passes from glass (n=1.5) to air (n=1)?
Use \\( \\sin \\theta_c = \\frac{n_2}{n_1} \\).
State True or False: Total Internal Reflection can occur when light travels from a rarer to denser medium.
Think about the direction of light travel.
What is the critical angle for water (n=1.33) to air?
Recall the refractive indices.
True or False: An evanescent wave can carry energy away from the interface.
Think about their properties during TIR.
At what angle should light strike a diamond (n=2.42) in order to undergo total internal reflection when passing to air (n=1)?
Start with the critical angle formula.
Describe the importance of TIR in modern optical applications, specifically in fiber optics.
Consider applications in telecommunications and medical devices.
