transeverse waves Flashcards
pulse
is a single disturbance that moves through a medium.
wave
is a regular repetitive disturbance that consists of a succession of pulses.
transverse pulse
is a single disturbance in a medium which oscillates perpendicularly to the direction of
the motion of the wave.
longitudinal pulse
A longitudinal pulse is a single disturbance in a medium which oscillates parallel to the direction of motion
of the wave.
transverse wave
is a wave in which the particles of the medium vibrate at right angles to the direction of
motion of the wave.
longitudinal wave
Longitudinal wave is a wave in which the particles of the medium vibrate parallel to the direction of motion
of the wave.
principle of superposition
The principle of superposition states that the algebraic sum of the amplitudes of two pulses that occupy
the same space at the same time.
interference
Interference takes place when two waves pass through the same region of space at the same time
resulting in the superposition of waves.
Constructive interference
Constructive interference is the phenomenon where the crest of one pulse overlaps with the crest of
another pulse to produce a pulse of increased amplitude.
Destructive interference
Destructive interference is the phenomenon where the crest of one pulse overlaps with the trough of
another pulse to produce a pulse of reduced amplitude.
Wavelength
Wavelength is the distance between two successive points on a wave that are in phase.
crest
Crest is the point on the wave where the displacement of the medium is at a maximum.
trough
Trough is the point on a wave where the displacement of the medium is at a minimum.
Points are in phase when
Points are in phase when they are separated by a whole number multiple of complete wavelengths.
Points are out of phase when
Points are out of phase when they are not separated by a whole number multiple of complete
wavelengths.
