Progressive waves and the wave equation
wave equation
Wave definitions
Wave speed
Wave features
trough
wave length
peak
amplitude
disturbance(vertical from the peak to the trough)
Propagation(half of the wave)
Wavelength is the distance between 2 peaks or 2 similar points
Frequency is the number of oscillations every second.It is measured in Hertz (Hz)
Amplitude is the maximum displacement from the equilibrium
The period of a wave is how long it takes for one oscillation
Sound in steel travels at 6000 m/s
Light in glass travels at 2x8^8
Sound in water travels at 1500 m/s
Sound in air travels at 336 m/s
Light in a vacuum travels at 3x8^8
Wave speed (v) = frequency (f) x wavelength (λ)
All electromagnetic waves obey this equation c=fλ
All electromagnetic however travel at the SAME SPEED in
a vacuum and air this is 3 x 10^8 m/s.(speed of light through a vacuum or air)
