chapter 29 homework

QuestionAnswer
What is light that bounces back a particle or wave that strikes a a boundary between two media? Reflected
What does the law of relfection state? It says that the angle of incidence is equal to the angle of reflection.
What is the normal? A line perpendicular to the point where the incident ray strikes the barrier and is drawn as a dashed line.
What kind of image does a plane mirror produce? A plane mirror produces only virtual images.
What kind of image does a concave miror produce and, what kind of mirrors are concave? A concave mirror produces an image that curves outward. A makeup mirror is a type of concave mirror.
What is diffuse reflection? Diffuse reflection is the reflection of light from rough objects.
What are reverberations and what do they have to do with acoustics? Reverberations are multiple rections of sound, and they help balance sound in an audiotorium or concert hall.
What is refraction? The bending of a wave as it crosses the boundary between two media at an angle.
What kind of image does a convex mirror produce, and what kinds of mirrors are convex? A convex mirror produces an image that curves inward. A security mirror and a traffic control mirror are two different kinds of convex mirrors.
What is the difference between light that is totally reflected and light that is partially reflected? Light that is totally reflected has all of it's light bounce back, and partially reflected light only has some. Also, light that is totally reflected needs a very rigid second surface while the partially reflected light only needs a less rigid surface.
When light shines perpendicularly on the surface of still water what percent is reflected? 2%
What is a real image? It is always inverted. Concave mirrors seen from far away are real images. They are formed by converging light rays and are displayed on a screen.
What is an image? It is a likeness or reproduction of an object.
What kind of image does a plane mirror produce, and what kinds of mirrors are plane? A plane mirror produces a flat image. Bathroom mirrors and dressing room mirrors are plane mirrors.
Whether a surface is a diffuse reflector or a polished reflector depends on what? The wavelength of the wave it reflects.

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.
