हिन्दीIn a Young's double slit experiment, if there is no initial phase difference between the light from the two slits, a point on the screen corresponding to the fifth minimum has path difference
View Answer & Solution
Correct answer · Option D
\( 9\frac{\lambda}{2} \)
Explanation
The condition for minimum path difference is \( \Delta x = (2n - 1)\frac{\lambda}{2} \). For the fifth minimum (\( n = 5 \)), \( \Delta x = (2(5) - 1)\frac{\lambda}{2} = 9\frac{\lambda}{2} \).
