Paragraph: Two plane harmonic sound waves are expressed by the equations. aligned & y₁(x, t)=A (0.5 x-100 t) & y₂(x, t)=A (0.46 x-92 t) aligned (All parameters are in MKS) Question: What is the speed of the sound?

Options

  1. A200 ~m / s
  2. B180 ~m / s
  3. C192 ~m / s
  4. D96 ~m / s

Correct answer

A. 200 ~m / s

Step-by-step solution

Speed of wave v= R or v= 100 0.5 or 92 0.46 =200 ~m / s
