| Question | Answer |
|---|---|
| Waves transmit _____________. | energy |
| Waves do not transmit ____________. | matter |
| vacuum | Empty space |
| These waves can transmit energy through a vacuum. | Electromagnetic waves |
| These waves can NOT transmit energy through a vacuum. | Mechanical waves |
| In transverse waves, particles of the medium move in a direction ______________ to the direction of the wave. | perpendicular |
| In a longitudinal wave, particles of the medium move in a direction _____________ to the direction the wave moves. | parallel |
| Another name for a longitudinal wave | Compression wave |
| In a surface wave, the particles of the medium move in a __________motion. | circular |
| amplitude | the measure of wave energy; the distance from the resting position to the highest or lowest points |
| energy of the wave varies in _______________ to the amplitude of the wave | direct proportion |
| The _________ the amplitude, the _________ the energy. | higher; greater |
| wavelength of a transverse wave | distance between crests and troughs of two consecutive transverse waves |
| crest | Highest parts of a transverse wave |
| Wavelength of a longitudinal wave | Distance between compressions and rarefactions |
| compression | Most tightly packed area of a longitudinal wave |
| rarefaction | Most spread out area of a longitudinal wave |
| frequency | Number of wavelengths that pass a point in a given amount of time |
| How are wavelength and frequency related? | Inversely proportional |
| The frequency of a wave _____________ as its wavelength ______________ OR it __________ as its wavelength __________. | Increases; decreases OR Decreases; increases |
| Shorter wavelength = _____ frequency = _____ energy | Higher; more |
| Longer wavelength = ______ frequency = _____ energy | Lower; less |
| Hertz (Hz) | Unit of measurement for frequency; one Hertz = one wave per second |
