Angle of refraction

  1. Nov 14, 2008 #1
    1. The problem statement, all variables and given/known data

    If the sound wave hits the cold air interface at an angle of 60, what is the angle of refraction? The speed of sound as a function of temperature can be approximated by v = (331 + 0.60T) m/s, where T is in Celcius.


    2. Relevant equations



    3. The attempt at a solution
    so i was thinking since the angle fo incident and angle of refraction are the same, will the angle of refraction in this care just be 60?

    WHY would you think that "the angle fo incident and angle of refraction are the same"?

    I think you will get more help on this in "physics homework" so I am moving it.
