Displacement distance from the equilibrium position in a particular direction
time taken for a full oscillation of one wavelength time pass a
Period
given point.

Frequency number of waves that pass through a point per second
Wavelength distance between 2 adjacent points on a wave
Amplitude maximum displacement of a wave from its equilibrium point
Phase difference difference in displacement of particles along a wave.
What are the axes on an horizontal time vertical voltage/amplitude
oscilloscope
when a wave bends at a boundary between two materials due to
Refraction
different in density causing it slow down or speed up.
What direction will refraction from air to a denser medium it will move towards the normal.
move towards From a denser medium to air it will refract away
What is the incidence light that is pointing towards and striking a surface
What is the refracted ray light that has entered a second medium
n=c/v n is the refraction index c is speed of light in a vacuum and
Refraction equation
v is speed of light in the medium.
Refraction index equation with sini/sinr = n, sini is the sin angle of incidence, sinr angle or
angles refraction and n is refraction index. This is snells law

Superposition
superpose, producing a single wave.
when two waves meet at a point, the resultant displacement of
Principle of superposition
the wave at that point is equal to the sun of displacements.
when two waves have the same frequency, same wavelength and
Coherence
are kept at a constant phase difference
when two coherent waves collide and combine. (Displacements
Constructive interference

when two coherent waves collide and cancel out. (Displacement
at the same points are added however since the phase
Destructive interference
difference is half a wavelength you get A + -A making 0

What types of waves can be traverse waves
polarised
particle oscillations only occur in one direction that is
perpendicular to the direction of the wave (propagation). Simple
What is polarisation
terms waves will only move in the direction perpendicular to the
polarisation lens
