    Thanks, as you can tell,I am a "starter" :smile:

    What is the frequency of the wave?

    1. A sound wave of the form s = sm cos(kx - ωt + φ) travels at 345 m/s through air in a long horizontal tube. At one instant, air molecule A at x = 2.00 m is at its maximum positive displacement of 6.30 nm and air molecule B at x = 2.09 m is at a positive displacement of 2.40 nm. All the...

    At what distance x do the waves have a phase difference of ___?

    All good to go, if you don't mind helping me with another problem or do I have to create another thread? In the figure, a sound of wavelength 0.600 m is emitted isotropically by point source S. Sound ray 1 extends directly to detector D, at distance L = 10.5 m. Sound ray 2 extends to D via a...

    At what distance x do the waves have a phase difference of ___?

    Thank you, I think I understand what I did wrong, hopefully my answers come out correct, will update after trying my hypothesis. :)

    At what distance x do the waves have a phase difference of ___?

    I was looking at an example which had the wave-length as 2 meters, I must have gotten confused. Can you point me in the right direction for solving it with the 1.8m wave-length? I'm honestly confused on what to do with the wavelength.

    At what distance x do the waves have a phase difference of ___?

    1. The figure shows two point sources S1 and S2 that emit sound of wavelength λ = 1.8 m. The emissions are isotropic and in phase, and the separation between the sources is d = 18.0 m. At any point P on the x axis, the wave from S1 and the wave from S2 interfere. Start with P very far away (x =...
