A diffraction grating is placed 1.00 m from a viewing screen. Light from a hydrogen lamp is passed through the grating, and the 656 nm wavelength first bright fringe is seen 60.0 cm to one side of the center.
What is the designation for the grating in units of lines/mm
The hydrogen lamp is replaced with a mercury lamp. Where will the mercury lamp’s 546 nm wavelength first bright fringe appear on the screen
(C) If we replace the diffraction grating with a double slit, with slit spacing of 0.05 mm where will the 546 nm first bright fringe appear?
D. What are the colors that correspond to the two wavelengths in this problem?
