Assume a lightbulb converts all of its energy to green light (this is not true, some is lost as heat). If the lightbulb is 60W, how many photons would it produce in 60s? Assume a wavelength for green light of 532nm. Hint: replace f in the photon energy equation with c/lambda
Although it is not possible, imagine a scenario where we could take the entire mass of a 1.1 kg wrench and covert it completely in to energy. How many MJ would this be? MJ
