Chapter 29 VOCAB

bouncing back of a particle or wave that strikes the boundary between two media Reflection
line perpendicular to a surface, incident rays and reflected rays make equal angles with the line the Normal
angle between an incident ray and the normal to a surface Angle of Incidence
angle between a reflected ray and the normal to a surface Angle of reflection
angle of incidence for a wave that strikes a surface is equal to the angle of reflection. This is true for both partially and totally reflected waves Law of reflection
image formed through reflection or refraction that can be seen by an observer but cannot be projected on a screen because light from the object does not actually come to a focus. virtual image
reflection of waves in many directions from a rough surface Diffuse reflection
Persistence of a sounds, as in an echo, due to multiple reflections. Reverberations
change in direction of a wave as it crosses the boundary between two media in which the wave travels at different speed Refraction
crest, trough, or any continuous portion of a two-dimensional of three-dimensional wave in which the vibrations are all the same way at the same time wave front
floating image that appears in the distance and is due to the refraction of light in Earth's atmosphere Mirage
he sepreation of light into colors arranged according to their frequencies, by interaction with a prism or diffraction grating Dispersion
minimum angles of incidence for which a light ray is totally reflected within a medium Critical Angle
the 100% reflection (with no transmission) of light that strikes the boundary between two media at an angle greater than the critical angle Total internal reflection
Transparent fiber, usually glass or plastic, that can transmit light down its length by means of total internal reflection Optical Fiber

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
