The angular size of the central maxima due to a single slit diffraction is a→\mathrm{a} \rightarrow slit width ))

Options

  1. Aλa\frac{\lambda}{\mathrm{a}}
  2. B2λ a \frac{2 \lambda}{\text{ a }}
  3. C3λ2a\frac{3 \lambda}{2 \mathrm{a}}
  4. Dλ2a\frac{\lambda}{2 \mathrm{a}}

Correct answer

B. 2λ a \frac{2 \lambda}{\text{ a }}

Step-by-step solution

Angular size of central maxima is 2 ×(λa)=2λa\times\left(\frac{\lambda}{a}\right)=\frac{2 \lambda}{a}
