The spectrum of light from heated up Helium gas has only a few wavelengths present. These are known as spectral lines. It includes a strong yellow line with a wavelength in a vacuum of 587.5 nm and a red line at 667.8 nm. What are the angular separations (in degrees) between these two spectral lines for all visible orders obtained with a diffraction grating that has 7350 grooves/cm? (In this problem assume that the light is incident normally on the grating.)

The two most prominent wavelengths in the light emitted by a helium discharge lamp are 686.7 nm (red) and 587.6 nm (yellow). Light from a helium lamp illuminates a diffraction grating with 750 lines/mm, and the light is observed on a screen 50 cm behind the grating. What is the distance between the first-order red and yellow fringes? Express your answer in cm.

Constants I Periodic Table Helium atoms emit light at several wavelengths. Light from a helium lamp illuminates a diffraction grating and is observed on a screen 50.00 cm behind the grating. The emission at wavelength 501.5 nm creates a first-order bright fringe 21.90 cm from the central maximum. We were unable to transcribe this image
