Types of Waves
A disturbance that transfers energy from one place to another without transferring matter.
What are waves?
The peak in a transverse wave.
What is a crest?
The unit frequency is measured in.
What is Hertz?
How someone perceives the energy of a sound wave.
What is loudness?
A wave that only travels through matter.
What are mechanical waves?
The maximum distance a wave moves from its rest point.
What is amplitude?
The number of times a pattern repeats itself in a given time.
What is frequency?
The amount of sound energy that passes through one square meter in one second.
What is intensity?
A wave in which the disturbance is perpendicular to the direction the wave travels.
What are transverse waves?
The part of a longitudinal wave where the particles are furthest apart.
What is a rarefraction?
Waves with higher frequency will have _________ wavelength.
The blank is shorter.
What is pitch?
A wave that causes particles to move parallel to the direction that the wave travels.
The distance between one point on a wave and the same point on the next wave.
What is wavelength?
6 wavelengths pass in 2 seconds.
A frequency of 3 Hz means what?
The measure of intensity of a sound.
What are decibels?
A longitudinal wave that can only travel through matter.
What are sound waves?
The part on a longitudinal wave where the particles are closest together.
What is compression?
The relationship between energy of a wave and frequency.
What is directly proportional?
A sound twice as loud (measured in dB).
What is an increase in in 10 dB?
