waves Flashcards
what are longitudinal waves
the direction of the vibrating particle move in the same way are the direction of the wave moving in
what are transverse waves
the direction of the particle vibrating is at a right angle to the direction of the wave moving
what is the meaning of frequency
number of waves per seconds
how do you solve frequency
f=N/t
how to find T
T=1/f
how to find speed
v=d/t
how to find speed of waves
v=fλ
what does waves transfer
energy
what waves does sound has
longitudinal
what waves does water and EM has
transverse
what does diffraction mean
when a wave can bend or pass through a gap or around a object.
what happens to high frequency waves when passing through a object
it not able to diffract a lot
what happens to low frequency waves when passing through a object
it will diffract a lot
what does refraction mean
when the direction of the wave or light change when it passes through on martial to another
what happens when a waves passes through a small gap
it diffracts more (spreads out more)
what happens when a wave passes through a big gap
it does not diffract and goes the sames way as it entered the gap
what does amplitude mean
the distance from thee centre to the the top (crest)
what does wave length mean
distance from one to the next wave at the same point
what are the main five waves characteris
wavelength amplitude frequency period speed
what is the name given to the top of the wave
crest
what is the name given to the bottom of the wave
trough
what are the two main formulas to find frequency
f=N/t
f=1/T
