Longitudinal Longitudinal waves Waves

AI Thread Summary

Young's equation, Lambda = ax/D, is applicable for calculating the wavelength of light from interference patterns. It can also be used for longitudinal waves, such as sound waves. The method for measuring the wavelength remains consistent across different types of waves. This demonstrates the versatility of Young's equation in wave physics. Understanding this application enhances the comprehension of wave behavior in various contexts.

Eta

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.

Thread 'Is space stretching or is new space being created?'

Do we even know? My understanding of dark energy is that particles come into existence, exert and outward force, then vanish. My problem with that is how, of course, then how does dark energy know to push everything in the same direction? The pressure exerted would be in all directions, even if the space was moving so why isn't stuff pushed all over the sky? Thanks - rev

Thread 'The Physics of unloading sand from a barge'

I think it's easist first to watch a short vidio clip I find these videos very relaxing to watch .. I got to thinking is this being done in the most efficient way? The sand has to be suspended in the water to move it to the outlet ... The faster the water , the more turbulance and the sand stays suspended, so it seems to me the rule of thumb is the hose be aimed towards the outlet at all times .. Many times the workers hit the sand directly which will greatly reduce the water...
