Waves and oscillations
Q: A sound source sends a sinusoidal sound wave of angular frequency 3000 rad / s and amplitude 12.0 nm through a tube of air. The internal radius of the tube is 2.00 cm. (a) What is the average rate at which mechanical energy is transported to the opposite end of the tube? If an identical wave and the original wave travel along the tube simultaneously, what is the total average rate at which they transport mechanical energy to the opposite end of the tube when their phase difference is (b) 0, and (c) 0.40 π rad?
