When an electron in the ion He makes a transition from an initial energy level labeled by the integer ni to a final energy level labeled by the integer ny, it emits light of a corresponding wavelength given by the following formula: 2R 1 Consider the following three transitions specified using the notation ni -> nf: 5 -+ 3 6 - 3 7 -> 3 If light from these transitions passes through a diffraction grating having 775 lines per millimeter and then hits a screen 1.2 meters away, what are the y-positions of the first-order spectral lines for each of these transitions? Write the smallest of these y-positions (in centimeters) in the answer box, and then draw a diagram of the spectral lines to scale (i.e. the relative spacing between the lines should be correct)
