When a wave reaches a boundary between 2 media what happens... some or all of the waves bounce back into the first medium
reflection the return of a wave back into its original medium
Law of reflection states that the angle of incidence and the angle of reflection are the same
normal a line perpendicular to the surface
angle of incidence angle between an angle of incidence and the normal to a surface
angle of reflection angle between reflected ray and the normal to a surface
plane mirrors produce only virtual images
virtual images are always right side up
Convex Curved outward and produce a smaller and farther away image
concave (close up) curved in up right lager and closer image
concave (far away) curved in inverted (real) smaller and farther away image

Paper encounters millions of tiny flat surfaces facing all directions so they are reflected in all directions can be seen from many directions
a smooth mirrior is only reflected in one direction can only be seen in certain directions
Sound energy is not reflected is absorbed or transmitted
An echo is reflected sound
more sound energy is reflected from rigid and smooth surfaces
What's the study of reflective properties of surfaces is acoustics

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.
