Two coherent sources whose intensity ratio is $64 :1 $ produce interference fringes. The ratio of intensities of maxima and minima is :
\[\begin {array} {1 1} (1)\;9:7 & \quad (2)\;8:1 \\ (3)\;81:49 & \quad (4)\;81 : 7 \end {array}\]

Four light sources produce the following four waves :(i) $y_1= a \sin(\omega t+\phi _1)$ (ii) $y_2= a \sin 2 \omega t $ (iii) $y_3= a' \sin(\omega t+\phi _2)$ (iv) $y_4= a' \sin(3 \omega t+\phi)$ Superposition of which two waves give rise to interference ?

In an interference arrangement similar to YDSE , Slits $S_1\;and \;S_2$ are illuminated with coherent microwave sources and are synchronized to have zero phase difference The slits are separates by distance $d= 150 \;m$. The intensity $I_0$ is measured as a function of $\theta$ where $\theta$ is defined as shown. If $I _0$ is max intensity, calculate $I_0$ for $\theta=90^{\circ}$
