a) If the period of oscillation of a given wave is 3.4 seconds and the wave is travelling at 12 m/s, what the wavelength of the wave? b) What is the frequency of the 4th harmonic of the wave from part (a)?

What is the difference in motion between a transverse and longitudinal wave? Which type(s) can be considered as having kinetic energy?

A string is 1.5 m long and the wave travels at 250 m/s on the string. 1) What's the fundamental wavlength of the wave on a string? 2) What is the fudamental frequency? 3) What is the frequency of the fourth harmonic?

The depth to an unusual layer of rock is to be determined at a particular place by bouncing an artificially generated seismic wave off it and receiving the echo at the surface. When this is done, the depth is given by the equation, h = (1/2) v t, in which h is the depth, v is the average velocity of the seismic wave, and t is the time that it takes for the wave to go down to the rock layer and return to the surface. If t = 0.350 +/- 0.10, and v = 2,000 +/- 10. meters per second, what is the possible error in the depth. (Show your work, and remember to express your results in the correct number of significant figures.)
