What type of interference is represented in the diagram?
Constructive
Destructive
What's happening at A?
Two crests are combining to create constructive interference.
A crest and a trough are combining to create destructive interference.
Two crests are combining to create destructive interference.
A crest and trough are combining to create constructive interference.
What is happening at B?
Two crests are combining to create constructive interference.
A crest and a trough are combining to create destructive interference.
Two crests are combining to create destructive interference.
A crest and a trough are combining to create constructive interference.
What type of interference do noise cancelling headphones use?
Constructive Interference
Destructive Interference
Sound waves in musical instruments or tubes create standing waves that enhance which type of interference to make louder sounds?
Constructive
Destructive
True or False? Two waves cannot exist in the same space or in the same medium at the same time.
True
False
Through which material does sound travel slowest?
Water
Paper
Aluminum
Air
None of the above
When a compression interferes with another compression, what occurs?
They counteract and the wave stops.
They combine to create a larger compression.
They combine to create a rarefaction.
None of the above.
When a crest and a trough interfere, what occurs?
They combine to create a higher amplitude wave.
They counteract and the wave either lessens or stops completely.
The wave changes into a longitudinal wave.
When 2 waves temporarily interfere with each other then resume their course of movement, which of the following is true?
They take on and keep a new amplitude based on the result of the interference until the end of the movement.
They are not affected by the interference and maintain their original amplitude throughout the movement.
Both waves are always counteracted and cease to exist.
They temporarily take on a new amplitude due to the interference but resume their original amplitude until the end of the movement.
If a medium for a mechanical wave is secured on both sides with one side remaining still and the other producing a continuous wave, which behavior does that wave exhibit?
Scatters (no pattern - moves in random directions throughout medium)
Reflects ( bounces back and forth throughout medium)
Transmits (continues to move through the medium in original direction)
Ceases to exist - the secured opposite end stops the energy flow of the wave
Listen to the recording of someone yelling in a tunnel. Why do we hear something after each yell?
Sound waves are striking the walls of the tunnel and bouncing off of the walls.
Sound waves are striking the walls of the tunnel and going into the walls (they are not passing all the way through).
Sound waves are striking the walls of the tunnel and going all the way through the walls.
Sound waves are striking the walls of the tunnel and being bent as they go through the walls.
The diagram shows two pulses of equal amplitude, A, approaching point P along a uniform string.
When the two pulses meet at P, the vertical displacement of the string at P will be
A
0
21 A
2A
The diagram represents a rope along which two pulses of equal amplitude, A, approach point P.
As the two pulses pass through point P, what is the maximum vertical displacement of the rope at point P?
2A
21 A
A
0
Two pulses, A and B, travel toward each other along the same rope, as shown.
When the centers of the two pulses meet at point X, the amplitude at the center of the resultant pulse will be
+1 unit
-1 unit
0
+2 units
Review: What is it called when a wave bounces off an object?
Reflection
Refraction
Diffraction
What is a general definition of wave interference?
When a wave bounces off an object
When more than on wave meet and interact in the same medium
When a wave bends around a corner
When a wave creates static
When 2 waves meet on the same medium, how do they interact?
They bounce off one another
They travel through one another
They refract off one another
