waves basic terminology

what do waves transfer

transfer energy but not matter which can be interpretet as meaningful information

what is the movement of waves called?

oscillation

describe graph

wave length the distance between two crests

crest - top of peak

trought - opposite of crest

second crest has the amplitude

at the end of graph equilibrium point

what is the distance in the displacement and distance graph

how far a wave can travel from the starting point

what is the displacement in the displacement and distance graph?

how far from the equilibrium point a wave has oscillated

what are the units of the wave speed eqution?

f=hz

h=m

v=m/s

what is frequency?

number of complete oscillations per second

what is time period + units?

the time taken for 1 complete oscillation in seconds

what is a transverse wave + examples?

a wave oscillating perpendicular to the direction of the energy transfer

e.g. light and radio waves

what is a longitudinal wave + examples?

a wave occulting parallel to the direction of energy transfer and some of it’s areas are compressed while others spread out

e.g.sound waves

what is amplitude

maximum displacement
