In a double slit interference pattern, the first maxima for infrared light would be:

Position of maxima from central maxima produced by a monochromatic light is directly proportional to its wavelength.

i.e. ${\mathrm{x}}_{\mathrm{n}} = \frac{\mathrm{n\lambda D}}{\mathrm{d}}$

As the wavelength of infrared light is greater than the green light, the first maxima for infrared light would be farther from the center than the first maxima for green light.
