Two sound waves of the same frequency have respective amplitudes of 3 units and 1 unit and are travelling in opposite directions in the same straight line. At a particular place in that line, the resultant wave will vary in loudness. The ratio of maximum loudness to minimum loudness is:
- 9/1
- 6/1
- 9/2
- 2/1
Answer
(D) 2/1
