Chapter 29:15 Quest.

QuestionAnswer
When a wave is totally reflected, how much of the energy bounces back? All of the energy.
Metal surfaces are what to light waves? Rigid.
If a candle is placed in front of a plane mirror, rays of light from the camdle are reflected from the mirror in which direction? All directions.
Real images are formed by converging light rays and can be displayed on a screen. These images are always what? Inverted.
More sound energy is reflected from what two surfaces than fron a soft and irregular surface? A rigid and smooth surface.
When light is incident on a rough surface, it is reflected in what type of direction? Many directions.
A smooth mirror is only reflected in one direction, a(n) what pattern? Orderly pattern.
When light rays hit a convex mirror straight on, do the reflected rays diverge outward or remain parallel with each other? They diverge outward.
If the angle of incidence is 25 degrees, then what is the angle of reflection. How is that possible? The angle of reflection would be 25 degrees, too. Because it is stated in the Law of Reflection
When light strikes glass perpendicularly, about what percentage of its energy is reflected? About 4%.
What type of materials are not as rigid to light waves? Glass and water
Where can the angle of incidence and the andgle of reflection be found? For the angle of incidence, it is found between the incident ray and the normal. For the angle of reflection, it is found between the reflected ray and the normal.
Where can a virtual image be found? It appears to be in a location where light does not really reach.
The law of reflection holds for curved mirrors. However, what two things are affected that makes the object and image no longer equal? The sizes and distances.
Virtual images in mirrors are images that seem to be in or behind the mirror. These images are always what? Upright.

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.
