All but two gaps within a set of venetian blinds have been blocked off to create a double-slit system. These gaps are separated by a distance of 3.1 cm. Infrared radiation is then passed through the two gaps in the
blinds. The angle between the central and the second-order maxima in the interference pattern is 0.54 degrees.
What is the wavelength of the radiation? Answer in units of ìm.
