In a single slit diffraction pattern, the distance between the plane of the slit and screen is 1.3 m . The width of the slit is 0.65 mm and the second maximum is formed at the distance of 2.6 mm from the centre of the screen. The wavelength of light used is
- A \(6500 Å\)
- B \(6000 Å\)
- C \(5200 Å\)
- D \(4600 Å\)
Answer & Solution
Correct Answer
(C) \(5200 Å\)
Step-by-step Solution
Detailed explanation
\(a \frac{y_m}{D} = \left(m + \frac{1}{2}\right)\lambda\) \(\lambda = \frac{a y_m}{D \left(m + \frac{1}{2}\right)}\)
