Waves

Physical Science Waves

TermDefinition
Wave rhythmic disturbances that carry energy through matter or space
medium material through which a wave transfers energy
mechanical wave is just a disturbance that propagate through a medium.
electromagnetic wave is simply light of a visible or invisible wavelength.
longitudinal wave the particles in the medium move parallel to the direction of the wave.
transverse wave the particles in the medium move perpendicular to the direction of the wave.
surface wave is often a combination of the two. Particles typically move in circular or elliptical paths at the surface of a medium.
Crest the highest point on a wave
trough the lowest point on a wave
wavelength the horizontal distance, either between the crests or troughs of 2 consecutive waves
amplitude measure of the energy in the wave, height of wave
rarefaction is the part of the longitudinal wave where the particles are spread apart.
compression the part of the longitudinal wave where the particles are crowded together.

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.
