refraction the bending of waves as they pass from one medium to another at an angle
standing wave a pattern of vibration that resembles a stationary wave
reflection the bouncing back of a wave when it meets a surface or boundary
constructive int interference that increases amplitude
destructive int interference that decreases amplitude
principle of superposition method of adding crests and troughs of interfering waves together to describe a new wave
beats sounds produced by the interference of sound waves that are used to tune piano strings
interference the combination of two or more waves that result in a single wave
nodes points in a standing wave that have no vibration due to destructive interference
sound Sound is what we hear when something vibrates (shakes back and forth) and sends waves through the air (or water or solids) to our ears
pitch the quality of a sound governed by the rate of vibrations producing it; the degree of highness or lowness of a tone.
infrasonic relating to or denoting sound waves with a frequency below the lower limit of human audibility
ultrasonic of or involving sound waves with a frequency above the upper limit of human hearing.
doppler an increase (or decrease) in the frequency of sound, light, or other waves as the source and observer move toward (or away from) each other. The effect causes the sudden change in pitch noticeable in a passing siren, as well as the redshift seen by astron

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.
