The equation of sound wave is y=0.0015 (62.4 x+316 t) . Find the wavelength of this wave

Options

  1. A0.2 unit
  2. B0.1 unit
  3. C0.3 unit
  4. DNone of these

Correct answer

B. 0.1 unit

Step-by-step solution

General equation of plane prograssive wave is given by y=a (k x+ t) Given equation y=0.0015 (62.4 x+316 t) ...(ii) Comparing Eqs. (i) and (ii), we get aligned k &=62.4 2 &=62.4 &= 2 62.4 =0.1 unit aligned
