F=L4πD2. The flux of light we receive from the Sun here at Earth (a distance of one astronomical unit or D=1 AU=1.5×10^8 km from the Sun) is called the "solar constant". It's measured to be F=1362 Watts per square meter.
Saturn is 10 AU from the Sun. What is the flux that Saturn receives from the Sun in Watts per square meter?

If you chip a tooth, most likely you will go to the dentist to have the missing material filled in. currently the material used to fill in teeth is a polymer that is flexible when put in, yet is hardened to the strength of a tooth after irradiation with blue light at a wavelength of 461 nm. what is the energy in joules for a photon of light at this wavelength?
