a. What is the length of an open tube that has the same fundamental frequency?
b. What is this frequency?
c. These two tubes are placed in a gas with a speed of sound greater than the speed of sound in air. Do the frequencies of their fundamentals remain equal to each other?
d. Do they increase or decrease?

-
v=2nl for the open tube and
v=4nl' for the tube closed ar one end
hence l=2l'.thus the open tube must be 100 cm
Then calculate the frequency assuming the vel as whatever given (330m/s etc)
As the v increases in the Gas the frequency increases too but equal for both
