Light is incident at an angle `phi` with the normal to a plane containing two slits of separation d. Select the expression that correctly describes the positions of the interference maxima in terms of the incoming angle `phi` and outgoing angle `theta`.

Light is incident at an angle phi with the normal to a vertical plane containing two narrow slits (S1 and S2) at separation d. The medium to the left of slit plane is air and wavelength of the incident light is lambda . The medium to the right of the slit plane has refractive index mu . Find all values of angular position (theta) of a point P where we will observe constructive interference. Wavelength of incident light is lambda .
