toward
Choose the correct answer... When light refracts into a substance in which it must slow down, the light raw will bend (toward or away from) a line perpendicular to the surface it strikes.
away from
Choose the correct answer... When light refracts into a substance in which it speeds up, the light ray will bend (toward or away from) a line perpendicular to the surface it strikes.

How do you remember the order of the rainbow?
There must be water droplets in the air, the sun must be shining behind you, and the sun must be at a certain angle.
In order for a rainbow to appear, what three criteria must be met?
converging, diverging
What are the two types of lenses?
Converging lenses focus light rays to a single point and diverging lenses bend light rays outward.
What are the differences between converging and diverging lenses?
too strongly
When you are nearsighted, you refract light too strongly or too weakly?
too weakly
When you are farsighted, you refract light too strongly or too weakly?
