Equation for sound waves

WebA sound wave produced by an ultrasonic transducer, moving in air, is modeled with the wave equation s(x,t) = 4.50nmcos(9.15 × 104m−1x−2π(5.00MHz)t). s ( x, t) = 4.50 nm cos ( 9.15 × 10 4 m − 1 x − 2 π ( 5.00 MHz) t). The transducer is to be used in nondestructive testing to test for fractures in steel beams. WebEquations [ edit] In what follows n, m are any integers ( Z = set of integers ); .
