6.6.1, Waves in air, fluids and solids Flashcards
how do oscillations in longitudinal waves move
how do they move in relation to the direction of energy transfer
side to side, from left hand to right hand
move parallel to the direction of energy transfer
how do oscillations in transverse waves move
how do they move in relation to direction of energy transfer
up and down
perpendicular (@ right angles to direction of energy transfer)
what are the regions of waves closer together and further apart called in longitudinal waves
closer together = compressions
further apart = rarefractions
what does the frequency of waves mean
what’s it measured in
no. of waves passing a point per second
hertz, 1hz = 1 wave per second
what is wavelength
what’s it measured in
distance from one point on a wave to the identical point on the next one
measured in meters
what is wavelength
what’s it measured in
distance from one point on a wave to the identical point on the next one
measured in meters
time period of a wave
what’s it measured in
time for wave to pass a given point or time for one complete oscillation
measured in seconds
the amplitude of a wave
what’s it measured in
