While we haven't really discussed this yet, there is actually a mathematical relationship that links wavelength and energy. This is a very famous equation and takes the form E = hc/\lambda where h = planks constant = 6.63 x 10^{-34} and c = the speed of light = 3 x 10^8 m/s. Use this equation to determine the energy of the following photons: A photon with a wavelength of 500 nm. E = blank1 - Numeric Answer Type your answer here J A photon with a wavelength of 840 nm. E = blank2 - Numeric Answer Type your answer here J _____________________________________________________ Now try and rearrange the E = hc/\lambda equation so that you can find the wavelength of a photon that has an energy of 5.15 x 10^{-19} J. \lambda = blank3 - Numeric Answer Type your answer here nm
