#### Definitions

speed According to Snell's law, as a light right ravels from one medium into another medium where the light's ____ is different, the light ray will change its direction unless it travels along the normal.
larger When light passes from one medium into another medium with a larger/smaller index of refraction, the ray bends towards the normal.
smaller When light passes from one medium into another medium with a smaller/larger index of refraction, the ray bends away from the normal.
real, inverted The image produced by a converging lens is real/virtual and upright/inverted when the object is outside the focal point.
virtual, upright The image produced by a converging lens is real/virtual and upright/inverted when the object is inside the focal point.
upright, virtual Diverging lenses always produce _____, _____ images.
Total internal reflection ______ _______ ________ can occur when light attempts to move from a material with a higher index of refraction to one with a lower index of refraction. If the angle of incidence is greater than the critical angle (90° with the normal), the ray is totally reflected at the boundary.
Mirages ______ and the visibility of the sun after it has physically set are naturally phenomena that can be attributed to the refraction of light in the Earth's atmosphere.
