Monochromatic light from a distant source is incident on a slit 0.750 mm wide. On a screen 2.00m away, the distance from the central maximum of the diffraction pattern to the first minimum is measured to be 1.35mm
Calculate the wavelength of the light (answer in nm).
A lens with an index of refraction of 1.60 is to be coated with a material (n = 1.39) that will make the lens nonreflecting for yellow-orange light (? = 515 nm) normally incident on the lens
