An organ pipe of length 50 cm, open at one end, has a fundamental frequency of 171 Hz. Calculate the speed of sound in the pipe. What is the wavelength v?

wavelength = 2m

Speed = 342m/s

Explanation:

The length of the pipe in terms of the wavelength is expressed as;

L = v/4 (For closed pipe)

v = 4L

Given

L = 50cm

L = 0.5m

Get the wavelength v;

v = 4(0.5)

v = 2.0m

Hence the wavelength is 2.0m

The speed of the sound in pipe is expressed as;

Fo = V/4L

Fo is the fundamental frequency

V is the speed of sound

L is the length of the pipe

171 = V/4(0.5)

V = 171 * 2

V = 342m/s

Hence the speed of the sound in pipe is 342m/s

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
