Problem

In a Young's double slit experiment, the intensities at two points, for the path difference

\frac{\lambda}{4}

and

\frac{\lambda}{3}

(

\lambda

being the wavelength of light used) are

I_1

and

I_2

respectively. If

I_0

denotes the intensity produced by each one of the individual slits, then

\frac{I_1 + I_2}{I_0} = \dots
