Waves - Coggle Diagram
Waves
Waves have measurable properties
crest
highest point or peak of a wave
trough
the lowest point or valley of a wave
Amplitude
how far a wave rises above or goes below its original position
wavelenghth
the distance from one crest to the next or the distance between one trough and the next
frequency
the number of waves passing a fixed point
wave speed
wave speed = wavelenth times frequency
Waves transfer energy
a wave
a disturbance that transfers energy from one place to another.
medium
any substance that a wave moves through
mechanical waves
waves that transfer energy through matter
transverse waves
a horizontal wave
longitudinal wave
a wave that travels in the same direction as the disturbance
Waves behave in predictable ways
relection
the bouncing back of a wave after it strikes a barrier
refraction
bending of a wave as it enters a new medium at an angle other than 90 degrees
diffraction
the spreading out of waves through an opening or around the edge of an obstacle
interference
the meeting and combining of waves
