Question 25 of 191

nn identical waves each of intensity I0I_0 interfere with each other. The ratio of maximum intensities if the interference is (i) coherent and (ii) incoherent is :

Show answer and solution

Answer: (D) nn

 (Maximum intensity) coherent interference  (Maximum intensity) coherent interference \frac{\text { (Maximum intensity) coherent interference }}{\text { (Maximum intensity) coherent interference }} =n2I0nI0=n=\frac{\mathrm{n}^2 \mathrm{I}_0}{\mathrm{nI}_0}=\mathrm{n}
