The single slit is 3.34 * [tex]10^{-5}[/tex] m wide .
In the single-slit diffraction experiment, we can observe the bending phenomenon of light or diffraction that causes light from a coherent source to interfere with itself and produce a distinctive pattern on the screen called the diffraction pattern.
Diffraction is evident when the sources are small enough that they are relatively the size of the wavelength of light.
Fringe width is defined as the distance between any two consecutive bright or dark fringes.
Using the formula ,
nλ = a sin θ
a = nλ /sin θ
a = (1) (631 *[tex]10^{-9}[/tex] ) / sin (12)
a = 3.34 * [tex]10^{-5}[/tex] m
