2 cards from this section. Quick, good the night before a test.
What is Snell's Law?
Refer back to the principle of light refraction.
How does light behave when it enters a denser medium?
Think about the angles and the normal line.
What does Snell's Law relate?
Think about how angles interact when light passes through different mediums.
True or False: Light bends away from the normal when entering a denser medium.
Consider the properties of the mediums involved.
Light passes from air to a liquid with a refractive index of 1.4 at an incidence angle of 50 degrees. Calculate the angle of refraction.
Remember to apply Snell's Law accurately.
You have a light ray that enters glass at 35 degrees and exits into air. Given that the refractive index of glass is 1.52, what is the exiting angle in air?
Work through the two transitions carefully.
