A source emits a sound of constant frequency, f. If this sound enters an environment where the speed of sound is greater f stays the same and:

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.

a singer practicing the vocal scale singing "do, re,mi,fa,so,la,ti,do" produces sounds

at progressively shorter lambda and higher frequency.

at progressively longer lambda and lower frequency

at progressively shorter lambda and lower frequency

at progressively longer lambda and higher frequency

at progressively higher frequencies but constant wavespeed and wavelength.

the wavelength emitted during a persons speech depend on several factors, including the dimensions of their mouth and related cavities. if a person has inhaled helium gas, the speed of the sound waves through this helium gas will be > so when they speak, the same wavelengths and this greater sound speed result in speech at frequencies that are

greater than for their normal speech in air

lower than for their normal speech in air

the same as for their normal speech in air.

unable to be heard by stationary observers

more than one of these is correct

to have resonance and a standing wave on the sting of a violin or guitar, for the displacement of the string there should be

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.

while drinking soda from a bottle, you pause periodically and irritate the people around you by blowing across the top of the bottle to make it toot. the more soda you have removed:

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

when you hold a seashell to your hear the "sound of the sea" can be heard. this is due to the:

sounds whose intensities are too small to be audible under normal conditions are enhanced by reflection within the shell producing noise like the ocean.

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 transmission through the solid walls of the shell, producing noise like the ocean.

At a fireworks display an exploding aerial bomb produces a sound intensity of 1.0E-2 w/m at a distance of 100 m from the explosion. the surface area for a sphere is 4pie R^2. what would be the total power output of this explosion, assuming it is uniform and unfocussed.

The external auditory canal of the human ear is about .027 m long with diamier of .007 m. If this is approximated as atube, closed at one end, with sound waves speed of 344 m/s this tube would have a resonant frequency of:
