What is the energy of one photon of this light?
In addition to continuous radiation, fluorescent lamps emit sharp lines in the visible region from a mercury discharge within the tube. Much of this light has a wavelength of 436 nm. What is the energy (in J) of one photon of this light?
It's Plancks Constant divided by the wavelength. Do the math. (And it probably wouldn't hurt anything if you tried reading your book, either ☺)
