Question:

In a double-slit experiment with monochromatic light and a screen at a distance of 1.50 m from the slits, the angle between the second-order maximum and the central maximum is 0.0230 rad. If the separation distance of the slits is 0.0350 mm, what are
(a) The wavelength and color of the light and
(b) The lateral displacement of this maximum?
