4 cards from this section. Quick, good the night before a test.
What is the formula for the refractive index?
Remember the components of Snell's law.
Define total internal reflection.
Think about how light behaves at different media boundaries.
What does the refractive index (μ) represent?
Think of how light behaves at different materials.
Is total internal reflection possible when light moves from a denser to a rarer medium? True or False.
Recall the conditions needed for total internal reflection.
A light ray strikes a glass interface at an angle of 30°. If the refractive index of glass is 1.5, what is the corresponding angle of refraction in the glass?
Rearrange Snell's Law to solve for the unknown angle.
If you have a prism made of material with a refractive index 1.67, and light hits it at the critical angle. How would this affect light traveling out of the prism?
Consider the relationship of the critical angle and its effect on specific incidences.
