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 |
