Waves
moving energy.
Transverse Waves
particles vibrate at right angles to the movement energy
Longitudinal Waves
particles vibrate in the same direction as the movement of energy.
Amplitude
height of wave from middle to a peak or trough.
Displacement
distance a particle moves from the centre.
Wavelength
length of one complete wave.
Time Period
time taken for one complete wave.
Frequency
number of waves that travel past a point in one second.
Wave Equation
speed = frequency x wavelength.
Reflection
bouncing of waves off a surface.
Incident Ray
ray of light hitting the mirror.
Reflected Ray
ray of light bouncing off the mirror.
Water Fronts
peaks of waves, always right angles to the wave direction.
Refraction
bending of a wave when it goes from one substance into another.
Diffraction
spreading out of a wave as it goes through a gap, or around an object.
How many types of wave are there
two; transverse and longitudinal
Frequency is ...
the number of waves that pass each second.
A crest is...
the top of the peak of a wavw
Wave speed =
Frequency x Wavelength
Frequency =
Wave speed / Wavelength
Wavelength =
Wave speed / Frequency
