A transverse wave composed of an oscillation electric field and a magnetic field that oscillates perpendicular to the electric field.
Electromagnetic Wave
When light or sound waves bounce off an obstacle.
Reflection
The angle of reflection equals the angle of incidence.
The Law of Reflection
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.
light comes in little packets.
Finish the sentence: The particle theory of light states that...
light is a wave.
Finish the sentence: The wave theory of light states that...
light has a dual nature with wavelike and particlelike characteristics.
Finish the sentence: The quantum-mechanical theory of light states that...
The speed of light is the ultimate speed limit.

orange
Which has greater wavelength; orange or green?
red
Which has greater wavelength; blue or red?

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?
