Beats

Two waves Y1=0.25sin⁡316tY_1 = 0.25\sin 316t and Y2=0.25sin⁡310tY_2 = 0.25\sin 310t are propagating along the same direction. The number of beats produced per second are

Show answer and solution

Answer: (a)

  1. f=ω2πf = \frac{\omega}{2\pi}, so beat frequency =ω1−ω22π= \frac{\omega_1 - \omega_2}{2\pi}
  2. =316−3102π=62π=3π= \frac{316 - 310}{2\pi} = \frac{6}{2\pi} = \frac{3}{\pi} per second
  3. So the answer is (a) 3π\frac{3}{\pi}.
