उत्तर

`I_0/4`

 

Total intensity coming from the source is I0  which is present at the central maxima. In case of two slits, the intensity is getting distributed between the two slits and for a single slit, the amplitude of light coming from the slit is reduced to half  which leads to 1/4th of intensity.
