1wavelength is the distance between a point on one wave and the same point on the next wavefrequency is the number of waves produced by a source each second. It is also
the number of waves that pass a certain point each second.
2REFLECTION: the change in direction of a wave once striking the boundary between two mediumsREFRACTION: the change in direction of a wave once it passes across the boundary from one medium to
another of varying density
3WAVES: a transfer of energy as a result of the vibrations/oscillations of particlesTRANSVERSE: wave oscillations are perpendicular to direction of wave transfer
4DIFFRACTION: When waves meet a gap in a barrier, they carry on through the gap. However, the waves spread out to some extent into the area beyond the gap.AMPLITUDE: the size of the wave
5WAVE SPEED: how far the wave travels forward (propogate)v = f × λ
6ELECTROMAGNETIC SPECTRUM: a continuum of all electromagnetic waves arranged according to frequency and wavelength.Radio waves Microwaves Infrared Visible Light Ultraviolet X-rays Gamma rays
