Part A A diffraction grating is to be used to find the wavelength of the emission spectrum of a gas. The grating spacing is not known, but a light of a known wavelength of 632.8 nm is deflected by 43.2" in the second order by this grating. Light of the wavelength to be measured is deflected by 49.1" in the second order. What is the wavelength of this light? AEd nmPart A Parallel light rays with a wavelength of 560 nm fall on a single slit. On a screen 3.50 m away, the distance between the first dark fringes on either side of the central maximum is 4.80 mm . What is the width of the slit? ? mm Submit Request
