QuestionAnswer
Wave is a repeating disturbance that transfers energy through matter or space
Medium is matter through which a wave travels
Mechanical wave are waves that can travel only through matter
Transverse wave particles in the medium moves back and forth at right angles to the direction that the wave travels
Longitudinal wave matter in the medium moves back and forth along the same direction that the wave travels
Crest are the high points of a transverse wave
Trough are low points of a transverse wave
Compression is the more dense region of a longitudinal wave
Rarefaction the less dense region of a longitudinal wave
Wavelength is the distance between one point on a wave and the nearest point just like it
Frequency a wave is the number of wavelengths that pass a fixed point each second
Period a wave is the amount of time it takes one wavelength to pass a point
Amplitude is a measure of the size of the disturbance from a wave
Refraction is the bending of a wave caused by a change in its speed as it travels from one medium to another
Diffraction is the bending of a wave around an object
Interference is the process of two or more waves overlapping and combining to form a new wave
Standing wave is a special type of wave pattern that forms when waves equal in wavelength and amplitude but traveling in opposite directions continuously interfere with each other
Node which are locations where the interfering waves always cancel
Resonance is the process by which an object is made to vibrate by absorbing energy at its natural frequencies

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.
