Question

a) Traveling waves propagate with a fixed speed usuallydenoted as v(but sometimes c). The waves are called _______________ if their waveformrepeats every time interval T.

The fundamental relationship among frequency, wavelength, andvelocity is

v=fλ.

This relationship may be visualized as follows: In 1 s,  f·(1s) cycles of the wave move past an observer. In thissame second the wavetrain moves a distance  v·(1s)  .

c) If the velocity of the wave remains constant, then as thefrequency of the wave is increased, the wavelength___________.

d) The difference between the frequency f and the frequency w is that f is measured in cycles per second or hertz (abbreviated Hz) whereasthe units for w are _______ per second.

e) Find an expression for the period of a wave T in terms of other kinematic variables.

f) What is the relationship between w and f?

g) What is the simplest relationship between the angularwavenumber k and just one of the other kinematic variables?
