MMS Waves

MMS Waves - Sound and Electromagnetic

Amplitude size of the wave, up and down (larger amplitude = louder sound or brighter light)
Intensity loudness - depends on the amplitude (larger amplitude = louder sound)
decibel (dB) unit used to measure sound
frequency how many waves pass in one second (how fast waves are traveling)
pitch the highness or lowness of a sound
velocity the speed and direction
tone quality what the tone sounds like (2 sounds can be different but still have the same pitch and loudness)
noise sound that has no set pitch or regular wave pattern, is often unpleasant
longitudinal wave also called compression wave. particles move side to side (like a spring) Sound moves this way
transverse wave particles move up and down creating a wave shape - light travels this way
reflection when waves hit something and bounce back - Example - light hits a mirror and bounces back or sound hits a canyon wall and echos
refraction waves bend because they are slowing down - Example - Light moving in air into water slows down when it hits water and bends
trough the bottom of a transverse wave
crest the top of a transverse wave
wavelength the distance between 1 wave and the next (1 full wave)
transmit let light or sound pass through (like a window)
absorb to take in (black absorbs all light)
photon the smallest possible particle of electromagnetic radiation
speed of light the fastest anything can move. 186,000 miles per second (670 million miles per hour), or about 300,000 kilometers per second in a vacuum.

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.
