Two slits in Young's experiment have widths in the ratio 1 : 25. The ratio of intensity at the maxima and minima in the interference pattern, \dfrac{{I}_\max}{{I}_\min} is:
Options
- A
- B
- C
- D
Correct answer
D.
Step-by-step solution
\dfrac{{A}_\max}{{A}_\min} = \dfrac{5 + 1}{5 - 1} = \dfrac{6}{4} = \dfrac{3}{2}
\dfrac{{I}_\max}{{I}_\min} = {\left(\dfrac{3}{2}\right)}^{2} = \dfrac{9}{4}
