A) 3
B) 6
C) \[3\pi \]
D) \[3/\pi \]
Correct Answer: D
Solution :
Comparing the given equations with the standard equation of wave. We have \[{{n}_{1}}=\frac{316}{2\pi }\] and \[{{n}_{2}}=\frac{310}{2\pi }\] hence number of beats is \[=\frac{316}{2\pi }-\frac{310}{2\pi }=\frac{6}{2\pi }=\frac{3}{\pi }\]You need to login to perform this action.
