Light of wavelength λ is incident on a slit of width d. The resulting diffraction pattern is observed on a screen at a distance D. The linear width of the principal maximum is then equal to the width of the slit if D equals
- \(\frac{\mathrm{d}}{\lambda}\)
- \(\frac{2 \mathrm{~d}}{\lambda}\)
- \(\frac{\mathrm{d}^{2}}{2 \lambda}\)
- \(\frac{2 \lambda^{2}}{\mathbf{d}}\)
Answer
(C) d ^ 2 2
