Document Summary

Physics 1501q - lecture 34 - harmonic waves, superposition, and standing waves. Direction of wave movement y = acos(kx - wt) Different signs for kx and wt the wave is moving in the positive x direction y = acos(kx + wt) Same signs for kx and wt the wave is moving in the negative x direction. The doppler effect (source slide 2 of 11/ lecture slides) Doppler shifted frequency f" = f*((1 (cid:541) 0 /v) / (1 (cid:541) s /v) Lower signs moving away from each other f" = doppler shifted frequency f = source frequency (cid:541) 0 = observer velocity (cid:541) s = source velocity v = the speed of light (~343 m/s) Two waves can meet an pass through each other without being altered (unlike particles) Constructive the two waves are said to be in phase (source http //physics. tutorcircle. com/waves/wave-interference. html ) Destructive the two waves are said to be out of phase (source http //physics. tutorcircle. com/waves/wave-interference. html )
