The wavelengths of two notes in air are 36 195 ~m and 36 193 ~m . Each note produces 10 beats per second separately with a third note of fixed frequency. The velocity of sound in air in m / s is

Options

  1. A330
  2. B340
  3. C350
  4. D360

Correct answer

D. 360

Step-by-step solution

Adding Eqs. (i) and (ii), we get aligned & v 18 =20 v & =360 ~ms ⁻¹ aligned
