Chapter 17 Vocabulary

TermDefinition
mechanical wave disturbance in matter that carries energy from 1 place to another.
medium the material through which the wave travels.
crest the highest point in the resting position.
trough the lowest point in the resting position.
transverse wave a wave that causes the medium to vibrate at right angels to the direction that the wave is traveling.
compression an area where the medium is placed close together.
rarefaction where the medium is spread out.
longitudinal wave vibration of the medium is parallel to the direction the wave is traveling.
surface wave waves that travel on the surface separated two media.
periodic motion motion that repeats at a regular time interval.
period the time required for the motion to go one full cycle.
frequency the number of complete cycles in a given time.
hertz cycles per second.
wavelength the distance between a point on one wave and the same point on the next cycle on the wave.
amplitude maximum displacement of the medium from its rest position.
reflection when a wave bounces off a surface that it cannot pass through.
refraction the bending of a wave as it enters a new medium.
diffraction the bending of a wave as it moves around an obstacle.
interference when two or more waves combine or overlap.
constructive interference when two or more waves combine to form a larger displacement.
destructive interference two or more waves combine to form a smaller displacement.
standing wave a wave that appears to stand in one place.
node the point on a wave that has no displacement.
antinode a point where a crest occurs midway bewteen two points.
electromagnetic waves transverse waves consisting of different electric fields.
electric field region of space exerts electric forces on charged particles.
magnetic field a region of space that produces magnetic forces.
electromagnetic radiation transfer of energy through electromagnetic waves.
photoelectric effect emission of electrons caused by light striking an object
photons packets of electromagnetic energy.
intensity the rate which a waves energy flows through a unit of area.
electromagnetic spectrum full range of frequencies of electromagnetic radiation.
amplitude modulation amplitude of wave is varied
frequency modulation frequency of wave is modified
thermograms uses infrared waves to detect heat.

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.
