Question

A person standing at a distance of 6 m from a source of sound receives sound wave in two ways, one directly from the source and other after reflection from a rigid boundary as shown in the figure. The maximum wavelength for which, the person will receive maximum sound intensity, is

  1. 4 m    
  2. fraction numerator 16 over denominator 3 end fractionm    
  3. 2 m    
  4. fraction numerator 8 over denominator 3 end fraction m    

The correct answer is: 4 m
