Reference no: EM13181395

A light sensitive substance in black and white photographic film is AgBr (silver bromide). Photons provide the energy necessary to transfer an electron from the anion, Br- to the cation Ag+ to produce elemental Ag and Br and thereby darken the film.

A. If a minimum energy of 2.00x10^5 J/mol is needed for this process, what is the minimum energy needed from each photon?

B. Calculate the wavelength of light necessary to provide photons of this energy

C. Explain why this film can be handled in a darkroom under red light.

Why is sb omitted : "Suppose Y = $200, C = $140, G = $25, x-m = -5, and T = $25. What is Sp? What is I?" Here is the answer:Yd = Y - T | C + Sp = Y - T | Sp = Y - T - C,Sp = Y - C - T = 200 - 25 - 140 = $35,I = Sp + (T - G) + (x-m) = $35 I = $35 + 0 - 5 = $30
