Interacting Waves
Two waves meeting/colliding in a medium create?
What is Interference?
This occurs when two sound waves of slightly different frequencies interfere?
What are beats?
A standing wave has nodes, where the amplitude is what?
What is zero?
when the observer is moving toward an object producing sound the frequency they hear is __
higher
If a wave with an amplitude of 5 meets another wave with an amplitude of 5, and the new amplitude is 10, this is a result of?
What is constructive interference?
This property of a sound wave determines its loudness?
What is Amplitude?
A standing wave in a bottle open at one end must have a node at . . . ?
What is the bottom?
the doppler effect occurs with what kind of waves
all kinds of waves
If two waves interact and they result in both waves cancelling out, this is a result of?
What is destructive interference?
The speed of sound(Air) at room temp?
What is 343m/s
When a sound wave is in a bottle (closed at one end and open at the other) the length of the wave must be this many times the length of the bottle.
What is 4 (four)?
The doppler effect only occurs when the object making sound does what
when the object is moving
If a crest and a trouph from two different waves with the same amplitude allign with each other, what interference will result?
What is destructive interference?
Higher pitch corresponds to this property of a sound wave?
What is higher frequency?
A standing wave in a pipe open at both ends must have what at each end of the pipe?
What is antinode?
the frequency heard is lower than the frequency produced by the source when
The source moves away from the observer
Two waves interfering, but moving in opposite directions with the same frequency and amplitude, create?
What is a standing wave?
If frequency increases and speed stays constant, this property decreases.
What is wavelength?
Standing waves form in pipes that are open at . . . ?
What is both ends?
The change in pitch due to the relative motion between a source of sound and the person hearing the sound
what is the doppler effect
