In an experiment of single slit diffraction pattern, first minimum for red light coincides with first maximum of some other wavelength . If wavelength of red light is \(6600\,\mathop A\limits^o\) , then wavelength of first maximum will be.....\(\mathop A\limits^o \)
- A \(3300\)
- B \(4400\)
- C \(5500\)
- D \(6600\)
Answer & Solution
Correct Answer
(B) \(4400\)
Step-by-step Solution
Detailed explanation
In a single slit experiment, For diffraction maxima, \(a\sin \theta = \left( {2n + 1\frac{\lambda }{2}} \right)\) and for diffraction minima, \(a \sin \theta=n \lambda\) According to question, \(\left(2 \times 1+1 \frac{\lambda}{2}\right)=1 \times 6600\)…
