Two waves $y_{1} = 0.35 sin (316 t)$ and $y_{2} = 0.35 sin (310 t)$ are propagating along the same direction. The number of beats produced per second are

Options:

Answer:

Solution:

According to question: $f_{1} = \frac{316}{2 π}$ and, $f_{2} = \frac{310}{2 π}$ Now, The number of beats heard per second $= f_{1} - f_{2} = \frac{316}{2 π} - \frac{310}{2 π} = \frac{3}{π}$
