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: How many times does an observer hear maximum intensity in one second?

TestHub · Accepted Answer

In one second number of maximas is called the beat frequency. Hence, f b ​ = f 1 ​ − f 2 ​ = 2 π 100 π ​ − 2 π 92 π ​ = 4 Hz
