- For light with a wavelength of 350 nm and with an intensity of /= 10-8 W/m², what is the number of photons/(m²s) in the light beam?Calculate the resonance frequency and the corresponding wavelength for an electron in a magnetic field of 0.330 T, the magnetic field commonly used in EPR.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?
