1 the pressure in a traveling sound wave is given by p 16, Ask an Expert

Academics

1.) The pressure in a traveling sound wave is given by: ?p = (1.6 Pa) sin ?[(1.30 m-1)x - (375 s-1)t].

(a) What is the pressure amplitude?

(b) What is the wave frequency?

(d) What is the speed of the wave?

m/s

2.) Two different sources emit sound waves in phase and with the same frequency of 400 Hz that travel in at 339 m/s. What would be the phase difference of the waves at a point that is 4.40 m from one source and 4.00 m from the other?

rad
