- http://www.gcsescience.com/pwav2.htm A traveling oscillation that has properties of frequency, wavelength, and amplitude Longitudinal waves When a longitudinal wave occurs, the particles of the material move backwards and fowards in the direction the wave is traveling in. Tranverse Waves Compression occurs when the coils of the spring are pushed togethor
Rarefaction occurs when the coils of the spring are pulled apart
The Wavelength of a longitudinal wave is recorded by the distance between the center of two compressions "When a transverse wave travels through a substance,
the particles of the substance are moved at right angles
to the direction in which the wave is traveling." - http://www.gcsescience.com/pwav3.htm The distance(m) between to crests or troughs Is the distance the wave has traveled during one complete cycle.
Wavelength is given the symbol .
This is the Greek letter lambda, pronounced lam-der.
Wavelength is measured in meters because it is a distance. Amplitude.. ..Is the maximum displacement from the average position.
Amplitude is a measure of how much energy the wave has. The period of a wave is defined as
the time taken for one complete cycle.
The velocity = x frequency.
This can be rearranged to give
Frequency = velocity ÷
The can be rearranged to give
= velocity ÷ frequency Equations Bibliography Period The period of a wave is defined as the time taken for one complete cycle.
The period = 1 ÷ frequency.
This can be rearranged to give
Frequency = 1 ÷ period. Frequency Frequency is defined as the number of complete cycles (complete waves) in one second.
Hertz is the unit of frequency (symbol Hz).
1 Hertz = 1 cycle per second. Wavelength 1. What are the 2 types of waves?
