- (a) Calculate the momentum of a visible photon that has a wavelength of 500 nm. (b) Find the velocity of an electron having the same momentum. (c) What is the energy of the electron, and how does it compare with the energy of the photon?For a given accelerating voltage, an electron microscope has a certain theoretical resolution. Suppose that instead of a beam of electrons you used a beam of protons, with the same accelerating voltage. How would this affect the theoretical resolution?Monochromatic radiation at 400 nm, produced by a laser, is completely absorbed by areaction mixture with a volume of 0.5 dm3. If the intensity of the radiation is 50 W,what amount of photons is absorbed in 10 minutes? What is the value of Ia? Show reasoning.
