5 cards from this section. Quick, good the night before a test.
What are the two main components of the Fresnel equations?
Think about what happens when light hits a surface.
Define reflectance in your own words.
Consider it in terms of light bouncing back.
What is the primary function of the Fresnel equations?
Consider what happens to light at the boundary of two materials.
True or False: The amount of light transmitted is equal to the amount reflected at the interface.
Think about how some light reflects and some passes through.
If light traveling from glass (n=1.5) to air (n=1) hits the interface at 60 degrees, calculate both the reflectance and the transmittance.
Use Snell's Law to find the refracted angle.
Consider a light beam polarized perpendicular to the plane of incidence striking a boundary at Brewster's angle. What can you determine about the reflectance?
Brewster’s angle involves using the refractive indices of the two media.
