Answer Details

When an open pipe is closed at one end, it produces the first fundamental note. The frequency of this note depends on the length of the pipe and the velocity of sound in air. The wavelength of the fundamental note must be four times the length of the pipe. The velocity of sound in air is given as P. Therefore, the frequency of the note is: f = P/4t where t is the length of the pipe. So, the correct option is: v/4t
