Paragraph: Two plane harmonic sound waves are expressed by the equations. ​ y 1 ​ ( x , t ) = A cos ( 0.5 π x − 100 π t ) y 2 ​ ( x , t ) = A cos ( 0.46 π x − 92 π t ) ​ (All parameters are in MKS) Question: What is the speed of the sound?

TestHub · Accepted Answer

Speed of wave v = R ω ​ or v = 0.5 π 100 π ​ or 0.46 π 92 π ​ = 200 m / s
