JEE Mains · Physics · STD 12 - 10. Wave optics
In a single slit experiment, a parallel beam of green light of wavelength \(550 \mathrm{~nm}\) passes through a slit of width \(0.20 \mathrm{~mm}\). The transmitted light is collected on a screen \(100 \mathrm{~cm}\) away. The distance of first order minima from the central maximum will be \(\mathrm{x} \times 10^{-5} \mathrm{~m}\). The value of \(\mathrm{x}\) is _______.
- A \(272\)
- B \(274\)
- C \(275\)
- D \(277\)
Answer & Solution
Correct Answer
(C) \(275\)
Step-by-step Solution
Detailed explanation
\(\mathrm{y}=\frac{\lambda \mathrm{D}}{\mathrm{d}}=\frac{550 \times 10^{-9} \times 100 \times 10^{-2}}{0.2 \times 10^{-3}}=275\)
