Physics chapter 16 quiz. Study for test please.
Lambda becomes longer.
Lambda becomes shorter.
Lambda stays the same if f is unchanged.
No. the speed of sound is a "constant" so f must change along with lambda.
No. the speed of sound, wavelength and frequency will all be unchanged.
At progressively longer lambda and lower frequency
At progressively shorter lambda and lower frequency
At progressively longer lambda and higher frequency
At progressively shorter lambda and higher frequency.
At progressively higher frequencies but constant wavespeed and wavelength.
Lower than for their normal speech in air
The same as for their normal speech in air.
Greater than for their normal speech in air
Unable to be heard by stationary observers
More than one of these is correct
3.2E-7 W
1.0E-2 W
3.1E2 W
1.3E3 W
None of these
Nodes at both ends
Loops or antinodes at both ends
A loop or antinode at one end and a node at the other end.
Nodes but no loops or antinodes since this motion would destroy the standing wave.
None of these
The lower the pitch of the resulting sound
The higher the pitch of the resulting sound
The pitch stays the same the stand waves just get longer
The pitch stays the same the standing waves just get shorter
None of these
High intensities
High frequencies
Long wavelengths
All of these
None of these
Marine environment in which the shell was formed
Shell blocking all other sound from reaching you.
Action of this shellular telephone that transmits sounds from distant shores to you.
Sounds whose intensities are too small to be audible under normal conditions are enhanced by reflection within the shell producing noise like the ocean.
Sounds whose intensities are too small to be audible under normal conditions are enhanced by transmission through the solid walls of the shell, producing noise like the ocean.
0.027 m
Less than 10 hz
3.2E3 hz
6.4E3 hz
1.3E4 hz
Wait!
Here's an interesting quiz for you.
