mechanical wave?
are the vibration of particles. they need a medium to travel through
electromagnetic wave?
do not required a medium to travel through
transverse wave
the direction of vibration is perpendicular to the direction in which the wave is travelling
longitudinal wave?
the direction of the vibration is parallel to the direction in which the wave is travelling
crest?
top of a wave
trough?
bottom of a wave
oscillation?
disturbance produced by one complite vibration of fhe source
wavelenght?
is the distance from any point on one cycle to the corresponding point on the next cylce
frequency?
the number of cycles passing any point per second
amplitude?
maximum distance of any particle from undisturbed position
dropped effect?
is the apparent change in frecuency of waves due to the relative motion between wave source and observer
polarisation?
is when the direction of vibration of a wave is restricted to one plane
diffraction?
is the spreading out of a wave as it moves thorugh a gap
