Answer:
The value is [tex]y = 0.00732 \ m[/tex]
Explanation:
From the question we are told that
The wavelength of each source is [tex]\lambda = 720 \ nm = 720 *10^{-9} \ m[/tex]
The distance from the pinhole [tex]D = 10 \ m[/tex]
The diameter is [tex]d = 1.2 mm = \frac{1.2}{1000} = 0.0012 \ m[/tex]
Generally from Rayleigh's criterion we have that the distance between the sources of light for their diffraction patterns is mathematically represented as '
[tex]y = \frac{ 1.22 * \lambda * D}{d}[/tex]
=> [tex]y = \frac{ 1.22 * 720 *10^{-9}* 10 }{ 0.0012}[/tex]
=> [tex]y = 0.00732 \ m[/tex]
