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 π/λ (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?

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
