Fluorescent Lightbulbs The most common fluorescent lightbulb converts ultraviolet light from mercury atoms to white light.
Part A
If an ultraviolet photon of wavelength 186 nm is emitted by a mercury atom and absorbed by the phosphor, what is the maximum number of red 664-nm photons that the phosphor can emit?
Please give a whole number and the answer is not 4 or 5.

9. Mercury atoms emit light at several wavelengths, see figure below. Light from a mercury lamp travels through a diffraction grating and is cast on a screen 50 cm away. The emission at wavelength 404.656 nm creates a first order bright fringe at 21.961 cm from the center maximum. What then is the wavelength of the bright fringe at a distance 34.991 cm from the center maximum. Note: the whole spectrum below is one mode or m. Mercury (Hg) 400...
