does length effect the pendulum? yes
the time for one cycle period
the pilled up energy sound barrier
when the listener can hear a boom sonic boom
how do u calculate the speed of a wave by multiplying the wavelength by the frequency
when the crest of 1 wave overlaps the trough of another destructive interference
a change in frequancy due to the motion of the source of wave the doppler effect
this wave occurs when a wave souce moves faster than the wave it produces bow wave
this wave occurs when an object moves faster than the speed of sound shock wave
a wiggle in time vibration
one complete back and forth swing cycle
a pictorial representation of a wave formed by swinging a pendulum or bouncing a spring sine curve
when the crest overlaps a crest constructive interference
sound waves are these kind of waves longitudinal
the distance from the top of one crest to the top of the next one wavelength
lower waves have less of this energy
back and forth vibrating motion simple harmonic motion
the maximum displacement from equilibrium amplitude
the high point on a wave crests
the unit of frequency hertz
the low points on a wave troughs
waves per second hertz
a 3 dimensional cone shape shock wave
forns when only half a wavelength or a multiple of half a wavelength fits exactly into the length of the vibrating medium standing wavee
occurs when waves from different sources arrive at the same point-at the same time interference patterns
nodes destructive
antinods constructive
standing waves have different frequencies
these waves are found in strings of musical instruments standing waves
sound and light waves also produce the doppler effect
does an ambulance coming towards you have a high or low pitched sound high
light source that moves towards you that has a higher frequency blue shift
light source moving away from you has a lower frequency red shift
this wave overlaps at the edges occurs only when the source travels faster than the wave speed bow waves
