If you recall, we have an energy equation for the energy of light at a certain frequency. Additionally, the frequency is often related to the wavelength via the speed of light.

#color(green)(E) = hnu = (hc)/color(green)(lambda)#

#=> color(blue)(E prop 1/lambda)#

So, now what do you think? Does a higher wavelength mean a lower energy? Yes/No?
