While discussing the propagation of sound through atmospheric air,one argued that the velocity of sound is `280 ms^(-1)` and said that he calculated it using Newton's formula.But another learner argued that velocity of sound is `330 ms^(-1)`.He justified his arguement by saying that he has applied Laplace corrected formula.
Write the formula used by the second learner.

While discussing the propagation of sound through atmospheric air,one argued that the velocity of sound is 280 ms^(-1) and said that he calculated it using Newton's formula.But another learner argued that velocity of sound is 330 ms^(-1) .He justified his arguement by saying that he has applied Laplace corrected formula. Using the above relation,show that velocity depends on temperature and humidity while is independent of pressure.
