The sun is a giant nuclear reactor, which emits light (electromagnetic radiation) at a range of frequencies. We human can only see visible light (400 – 700 nm), because its absorption results in a conformational change in the retinal molecule, which triggers a neural signal. a. What is the frequency of a 500 nm visible photon? b. How much energy in J does a 500 nm visible photon carry? С. A typical chemical bond has an energy of 5x10-19 J. Would a visible photon at 500 nm be sufficient to break a chemical bond? d. How about a UV (200 nm) photon? Indeed, UV light can damage DNA, the genetic material in our body, leading to mutations and possibly cancer.
