General Properties of Waves
Mrs. Gergel 2014

Properties of waves Waves can carry a little energy or a lot of energy
They also vary in length and speed Basic properties of waves are: amplitude, wavelength, frequency, and speed

Amplitude Amplitude- maximum distance the medium carrying the wave moves away from its rest position Measure of how much a particle in the medium moves when disturbed by the wave Amplitude of the wave is a direct measure of its energy The farther the medium moves as it vibrates the larger the amplitude

Amplitude of a transverse wave
The amplitude of a transverse wave is the maximum distance the medium moves up or down from its rest position Amplitude can be found by measuring the distance from the rest position to a crest or a trough Amplitude Rest position

Amplitude of a longitudinal wave
Amplitude of a longitudinal wave is a measure of how compressed or rarefied the medium becomes High energy vibrations cause the compressions to be very crowded Crowded compressions and uncrowded rarefactions mean that the longitudinal wave has a large amplitude Crowded compressions Uncrowded rarefactions

Wavelength A wave travels a certain distance before it starts to repeat The distance between two corresponding parts of a wave is its wavelength

Wavelength of a transverse Wave
Find the wavelength of a transverse wave by measuring the distance from crest to crest or trough to trough. This also works from rest position to rest position wavelength

Wavelength of a longitudinal wave
You can find the distance of a longitudinal wave by measuring the distance from one compression to the next wavelength

Frequency Frequency is the number of complete waves that pass a given point in a certain amount of time Frequency can also be described as the number of vibrations per second Frequency is measured in units called hertz (Hz) Hertz = # wave/ second

Speed Sound and light waves travel at different speeds
The speed of a wave is how far the wave travels in one unit of time, or distance divided by time Speed is measured in meters per second or m/s The speed, wavelength, and frequency of a wave are related to each other by a mathematical formula

Formulas Speed= Wavelength x Frequency
If you know any two of the quantities in the speed formula, you can calculate the third Frequency= Speed/ wavelength Wavelength= Speed/ Frequency In a given medium and under the same conditions, the speed of the wave is constant
The text passage is an educational presentation on the general properties of waves, including definitions and explanations of amplitude, wavelength, frequency, and speed, along with the relationships between these properties.
