Homework Help: Various questions regarding sound waves(thanks!)

  1. May 29, 2010 #1
    1. The problem statement, all variables and given/known data

    Reflection can you list some materials that reflect more than others and for what specific reason does one material reflect more than the other

    Refraction why do different mediums have different critical angles

    After the sound refracts OR diffracts, how does it effect the wavelength

    How does diffraction actually work, like.. does the climate effect the way waves go through obstacles and diffract, if so how?

    Does wave length effect how the wave is diffracted if so, does that have any relation to long wave lengths refusing to reflect so they refract, curve into the hollow space which diffracts?(If this is all wrong can someone please tell me how waves actually diffract and why)






    2. Relevant equations
    wave velocity = frequency * wave length


    3. The attempt at a solution

    Read the textbook, what more can i do... please help
