Science Ch. 24

TermDefinition
Infrared Waves Wavelengths between 0.001 meters and 700 billionths of a meter
Speed divided by frequency= wavelength how to calculate a wavelength
intensity the amount of energy that a wave carries past a certain area each second
pitch the human perception of the frequency of sound
ultraviolet waves Wavelengths between 400 billionths and 10 billionths of a meter
wave disturbance that moves through matter and space and carries energy
transverse wave Particles in matter to move back and forth at right angles to direction in which the wave travels
refraction the change in direction of a wave when it changes speed as it travels from one material to another
diffraction the bending of waves around an object
crest high point in a wave
trough low point in a wave
Wave speed = wave length x frequency wave speed equation
hertz the SI unit of frequency, equal to one cycle per second.
it gets louder What happens to a wave (speed) as it is in air & then hits water?
compressional wave causes particles in matter to move back and forth along the same direction in which the wave travels
air What “medium” does a wave travel the slowest in?
middle ear sound amplifier and eardrum vibrates
echolocation locating objects by sound bouncing off of them
decibels the intensity of sound waves
the normal conservation 50 dm
because the sounds do not reflect off of sot surfaces Why do theaters put curtains on the wall?
ultraviolet waves Vitamin D needs what kind of light?
wavelength Frequency is proportional with what?
visible light wavelengths that are visible to the human eye
wavelength distance between one point on a wave and the nearest point moving with the same speed and direction
electromagnetic spectrum the complete range of electromagnetic wave frequencies and wavelengths
reverberation repeated echoes

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.

To see how well you know the information, try the Quiz or Test activity.
