The width of one of the two slits in a Young's double slit experiment is three times the other slit. If the amplitude of the light coming from a slit is proportional to the slit-width, the ratio of minimum to maximum intensity in the interference pattern is \(x: 4\) where \(x\) is ..... .
- A \(1\)
- B \(1.4\)
- C \(14\)
- D \(10\)
Answer & Solution
Correct Answer
(A) \(1\)
Step-by-step Solution
Detailed explanation
Given amplitude \(\propto\) slit width Also intensity \(\propto(\text { Amplitude })^{2} \propto\) (Slit width \()^{2}\) \(\frac{{I}_{1}}{{I}_{2}}=\left(\frac{3}{1}\right)^{2}=9 \Rightarrow {I}_{1}=9 {I}_{2}\)…
