24.3 Gratings: an application of interference
Laser light on grating 2 Light of wavelength 630 nm passes through a grating and then onto a screen located several meters from the grating. The 1st order bright band is located 0.28 m from the central maximum. Light from a second source produces a band 0.20 m from the central maximum. Determine the wavelength of the second source. Show your calculations. Hint: If the angular deflection is small, tan
