A chamber that can be filled with different gases has placed in it a source of sound that in air produces a frequency of 200 Hz and a microphone to pick up the sound for frequency analysis.First the chamber is filled with helium (speed of sound 1 000 m/s at room conditions),then the helium is replaced with oxygen (speed of sound 330 m/s at room conditions),and then finally the helium is replaced with carbon dioxide (speed of sound 269 m/s at room conditions).In which gas is the highest frequency of sound found by the microphone during this experiment?
A)helium
B)oxygen
C)carbon dioxide
D)They all have the same frequency of sound.
