The value of the alpha factor for photons is

In the 1980s, the term picowave was used to describe food irradiation in order to overcome public resistance by playing on the well-known safety of microwave radiation. Find the energy in MeV of a photon having a wavelength of a picometer.

If an average of 10000 photons are detected per mm2 the probability of detecting between 9800 and 10200 counts in any exposed mm2 is approximately: a) 59 b) 75 c) 89 d) 95 e) 99

An electron is orbiting in the n = 3 orbit of an hydrogen atom. It is promoted by absorption of light energy to the n = 4 level. The Rydberg constant is R = 1.097 x 107 m-1. What is the wavelength of the light absorbed? Select one: a. 763 nm b. 427 nm c. 1.094 μm d. 1.875 μm Clear my choice   ◀︎ Workshop week 11 2020 Fission and Fusion Solutions
