The waves are vibrations that propagate. The ideal form of a wave motion sinusoide will follow. In addition to electromagnetic radiation and gravitational radiation, which may be able to walk through a vacuum, there are waves on a medium (which because of changes the shape can generate elastic restoring forces) where they can run and can move the energy from one place to another without causing the particles of the medium move permanently; i.e. There is no displacement en masse. In fact, any special point oscillating around one particular position can have an effect on the penis.
A medium called:
linear if different waves at any particular point in the medium can be summed up,
limited if restricted, otherwise it is called unlimited
physical characteristics of uniform if not changed at different points
isotropic in its physical characteristics if the "same" in different directions
The Wavelength
The wavelength is the distance between repeating units of a wave pattern. Usually have denoted the letter lambda (λ) Greece.
In a sine wave, the wavelength is the distance between the peaks.
The x Axis represents length, and I represent the quantity varies (e.g. air pressure for a sound wave or electric or magnetic field strength for light), at a point in the function of time x.
Wavelength λ has an inverse relationship to frequency f, number of peaks to pass a point in a given time. Panjan wave is equal to the speed of the wave divided by the frequency of the wave. When dealing with electromagnetic radiation in a vacuum, this speed is the speed of light c, untuku signal (waves) in the air, it is the speed of sound in air. Connection is::
λ = {c}: {f}
λ = wavelength of a sound wave or electromagnetic waves
c = speed of light in a vacuum = 299, 792.458 km/d ~ 300.000 km/d = 300,000,000 m/s or
c = speed of sound in air = 343 m/s at 20 ° C (68 ° F)
f = the frequency of the wave
