5 cards from this section. Quick, good the night before a test.
What is refraction?
Think of how light behaves when moving between air and water.
What does Snell's Law describe?
Remember the formula involving angles and indices!
What does Snell's Law relate?
It involves the ratios of angles and their respective indices.
True or False: A light ray can cross into a rarer medium from a denser medium at any angle.
Consider what's happening at that critical angle.
A light beam from air hits a glass surface at a 60-degree angle. Calculate the angle of refraction. Assume the refractive index of air is 1.00 and glass is 1.50.
Make sure to convert your values and solve step by step.
Explain why diamonds sparkle more than other gems using the principles of refraction and total internal reflection.
Think of the angles of incidence and reflection that maximize sparkle!
