6.6
waves
Transversewaves
Ripple on a water surface
Longtiudinal
Sound waves travelling through air
diagram
The disturbance moves back and forth at the start of the wave
Amplitude - The distance a partical moves from its undisturbed rest position
diagram
Wavelength - Distance from one complete wave
Frequency - number of waves per second ( Hertz)
Time - for one wave to pass a certain point
Equation
T = 1/F
T = time period
F = Frequency
WAVE SPEED = FREQUENCY X WAVELENGTH
Reflection
diagram
Reflaction
Change in density causes change in speed = change in direction
