The intensities of two sound sources emitting same frequency are in the ratio 16 : 9. Find the ratio of the intensities of maxima to minima when the sound waves produced by these sources undergo superposition.

Answer:

Solution:

$\frac{I _{ma x}}{I _{min}} = \frac{( I _{1} + I _{2} ) ^{2}}{( I _{1} - I _{2} ) ^{2}} = \frac{( 4 + 3 ) ^{2}}{( 4 - 3 ) ^{2}} = 49$ .
