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).
The third-order fringe of 650 nm light is observed at an angle of 17° when the light falls on two narrow slits. How far apart are the slits
