TermDefinition
Mechanical Wave A disturbance in matter that carries energy from one place to another.
Medium The material trough which a wave travels.
Crest The highest point of the wave above the rest position.
Trough The lowest point below the rest position.
Transverse Wave A wave that causes a medium to vibrate at right angles to the direction in which the wave travels.
Compression An area where the particles in a medium are spaced close together.
Rarefaction An are where the particles in a medium are spread out from each other.
Longitudinal Wave A wave in which the vibration of the medium is parallel to the direction the wave travels.
Surface Wave A wave that travels along a surface separating two media.
Periodic Motion Motion that recurs over and over and the period of time required for each recurrence remains the same
Period An amount of time
Frequency The number of occurrences within a given time period
Hertz The unit of frequency
Wavelength The distance between corresponding points on adjacent waves
Amplitude The maximum distance the particles of a medium move away from their rest positions as a wave passes through the medium
Reflection The action of a wave bouncing off an object
Refraction The bending of a wave caused by a change in its speed as it moves from one medium to another
Diffraction The bending of waves around a barrier or through an opening
Interference A wave interaction that occurs when two or more waves overlap
Constructive Interference The interference that occurs when two waves combine to make a wave with a larger amplitude
Destructive Interference The interference that occurs when two waves combine to make a wave with a smaller amplitude
Node A point on a standing wave that has no displacement from the rest position.
Intensity The amount of energy in a light or sound wave, which we perceive as brightness or loudness, as determined by the wave's amplitude
Electrogmagnetic Waves Transverse waves consisting of changing electric fields and changing magnetic fields.
Electric Field A region of space exerts electric forces on charged particles.
Magnetic Field A region of space produces magnetic forces.
Electromagnetic Radiation The transfer of energy by electromagnetic waves traveling though matter or across space.
Photoelectric Effect The emission of electrons from metal caused by light striking the metal.
Photons Packets of electromagnetic energy.
Intensity The rate at which a wave's energy flows through a given unit of area.
Electromagnetic Spectrum The full range of frequencies of electromagnetic radiation.
Amplitude Modulation When the amplitude of a wave is varied, and the frequency remains the same.
Frequency Modulation When the frequency of a wave is varied, and the amplitude remains the same.
Thermograms Color-coded pictures that show variations of the temperature.
Antinode A point where a crest or trough occurs midway between two nodes.

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.
