Velocity Of Sound

Now our aim is to find the fundamental length of the Bansuri, i.e., The Lowest pitch-Pa

But before going to that section we must know about the velocity of the sound. The velocity of the sound is generally considered as 331 m/s for rough calculation. The Velocity of the sound depends of the atmospheric temperature. The accurate formula for the Velocity of the sound is

                             C = 331.5 x Square Root [1 + ( T/273)]

                                                                             Where C = Velocity of the sound in m/s
                                                                                         T = Temperature in Celsius 



For example if the Temperature is 25 degree in winter, the Velocity of the Sound will be 343.42 m/s and when the temperature changes to 40 degree in  summer , the velocity of the sound will be 354.95 m/s

You can see from the above example that pitch changes due to the temperature variation, because the Velocity of the sound changes with the temperature, In the next entry we will see the correlation between the speed of the sound and Fundamental Pitch (Lowest Frequency)  and Fundamental length.
