How many times more energy is associ-
ated with a 282 nm ultraviolet photon than a
5494 nm microwave photon?
E = hc/wavelength
Convert wavelength to meters; i.e., 282E-9 and 5494E-9
However, you really don't need to go to that much trouble if you note that hc is constant; therefore, 5494/282 = ? The 282 nm has more energy than the 5494 nm
