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?
