WAVES

WAVES. W aves difference with oscillation. W aves that travel within or with a medium. As a wave propagates, it carries energy. The energy in light waves from the sun warms the surface of our planet; the energy in seismic waves can crack our planet's crust.

Chapter 13. Mechanical waves. Traveling waves. When you perturb a medium a wave often spreads out. Transverse Waves. If we perturb again and again we create a series of pulses. One can do the same with a spring or a rope. Longitudinal Waves. kinds of waves. mechanical waves

General Doppler Formula (Serway convention)

General Doppler Formula (Serway convention). f s = frequency emitted by source v S =Velocity of source. f L = frequency received by listener v L =Velocity of listener. f L = frequency received by listener v L =Velocity of listener.

Chapter 21

Chapter 21. Superposition and standing waves. http://www.phy.ntnu.edu.tw/java/waveSuperposition/waveSuperposition.html. When waves combine. Two waves propagate in the same medium Their amplitudes are not large Then the total perturbation is the sum of the ones for each wave.

Potential Energy

Potential Energy. Length hence dl-dx = (1/2) (dy/dx) 2 dx dU = (1/2) F (dy/dx) 2 dx potential energy of element dx y(x,t)= y m sin ( kx- ? t) dy/dx= y m k cos(kx - ? t) keeping t fixed! Since F= ?v 2 = ?? 2 /k 2 we find dU=(1/2) ?dx ? 2 y m 2 cos 2 ( kx- ? t)
