In a single slit diffraction of different light of wavelength
$\lambda$ by a slit of with t_1, the size of the central maximum on a
screen at a distance t_2 is

Show answer and solution

t_{1}sin\theta = \lambda

\theta = \lambda/t_{1}

Width of central Max.

y = 2t_{2}\theta + t_{1}

y = \frac{2t_{2}\lambda}{t_{1}} + t_{1}
