In double slit experiment, instead of taking slits of equal widths, one slit is made twice as wide as the other. Then in interference pattern
- A the intensity of the maxima decreases and the minima has zero intensity.
- B the intensity of maxima decreases and that of the minima increases.
- C the intensity of the maxima increases and the minima has zero intensity.
- D the intensities of both the maxima and the minima increase.
Answer & Solution
Correct Answer
(D) the intensities of both the maxima and the minima increase.
Step-by-step Solution
Detailed explanation
\(I_{\min } \propto(a-a)^2\)
Later,
\(I_{\min } \propto(2 a-a)^2\)
Clearly, the intensity of minima increases,
Again, \(I_{\max } \propto(a+a)^2\)
Later,
\(I_{\max } \propto(2 a+a)^2\)
Clearly, the intensity of maxima increases.
