Refraction and Snell's Law | Geometric optics | Physics | Khan Academy

How is the incident angle related to the reflected angle in the law of reflection?

• The incident angle is greater than the reflected angle

• The incident angle is less than the reflected angle

• The incident angle is equal to the reflected angle

what is it called when light moves through one substance and another then bends

• reflection

• refraction

• incidence

What does light do when it enters a different media at an angle?

• It continues straight through the material

• It bends as it enters the material

What is the definition of an interface? Check all that apply

• Where a material gets "in her face".

• An interface is where two different materials touch each other

• An interface is a surface separating two phases of matter, each of which may be solid, liquid, or gaseous.

What happens when the right side is moving faster than the left side?
