2 cards from this section. Quick, good the night before a test.
What is refraction?
Think about the bending of light when it enters different substances.
What is Snell's Law?
Check the proportion of sine functions involving the angles.
What does the refractive index symbolize?
Think about how it affects light transitioning between substances.
Total internal reflection occurs when light...
Remember when light cannot escape and is fully reflected.
An object is placed at 30 cm in front of a convex lens with a focal length of 25 cm. Calculate the image distance and determine if the image is real or virtual.
Apply the lens formula carefully considering the sign convention.
Light travels from air (n = 1.0) into glass (n = 1.5). If the incidence angle in air is 45°, find the angle of refraction in the glass.
Make sure to use calculator appropriately for finding sine inverse.
