Unformatted text preview: Homework #2 1) What are the definitions of polarization, wavelength and wavenumber? Polarization has to do with the relative direction of the particle motion and the wave motion. There are two general types of polarization, transverse and longitudinal. For transverse polarization waves , such as waves on strings, the particle motion is at right angles to the wave motion. For longitudinal polarization , the particle motion and wave motion are in the same direction. For more on this see question 5. Wavelength describes the spatial period for a harmonic wave (harmonic meaning a wave that is described by the sine/cosine functions). Given the wavelength l (which has the units of meters) the wavenumber is determined by the simple definition: k=2 / (and has units of radians per meter). 2) What is the relationship between pressure and force? What is the relationship between mass-density and mass? What are the units for each of these four quantities?...
