A slit of width \(10 \times 10^{-7} \mathrm{~m}\) is illuminated by light of wavelength \(500 \mathrm{~nm}\). Angular position of the first minimum is
- A 30\(^\circ\)
- B \(\dfrac{1}{2}^0\)
- C 60\(^\circ\)
- D 1\(^\circ\)
Answer & Solution
Correct Answer
(A) 30\(^\circ\)
Step-by-step Solution
Detailed explanation
The condition for the first minimum in a single-slit diffraction pattern is given by \(a \sin \theta = n \lambda\), where \(a\) is the slit width, \(\theta\) is the angular position, \(n\) is the order of the minimum, and \(\lambda\) is the wavelength of light. Given values are…
