Hi

I have learned at school that we can use Young's equation
Lambda = ax/D
to calculate the wavelength of light from an interference pattern
I'm wondering if this equation also works for longitudinal waves?

Thank you for your help

Yes it does, the wavelength of sound waves is measured in this way.
