Question #104073

The speed of sound V in a medium depends on it's wavelength , the young modulus E, and the density p, of the medium. Use the method of dimensional analysis to derive a formulas for the speed of sound in a medium .

Expert's answer

Young's modulus *E* is measured in kg m^{−1} s^{−2}

Density *ρ* has units of kg m^{-3}

Wavelength *λ* has units of m.

Since the speed of sound is measured in m s^{-1}, we can try to combine the quantities to get m/s:

The wavelength is not necessary.
