The rays of the Sun that cause tanning and burning are in the ultraviolet portion of the electromagnetic spectrum. These rays are categorized by wavelength: UV-A radiation has wavelengths in the range of 320–380 nm, whereas UV-B radiation has wavelengths in the range of 290-320 nm. Calculate the energy of one quantum of light with a wavelength of 290 nm and the energy of a quantum with a wavelength of 360 nm. (Hint first convert wavelength to frequency).Which have greater energy, UV-A radiation or UV-B? Does the amount of energy for each seem small? Why? A typical indoor tanning bed uses 97% UVA and 3% UVB. If the lights used only produced UV radiation would you feel hot while you were tanning?
