What is the energy of an electron with wavelength?
Solution: λ = h/p, E = p2/(2m), p = √(2mE), λ = h/√(2mE). The energy of the electron is 25000 eV * 1.6*10-19 J/eV = 4*10-15 J.
What is the wavelength of Proton?
The de Broglie wavelength of a proton (charge = 1.6×10-19C.
What is the wavelength of an electron beam?
The wavelength of electrons is much smaller than that of photons (2.5 pm at 200 keV). Thus the resolution of an electron microscope is theoretically unlimited for imaging cellular structure or proteins. Practically, the resolution is limited to ~0.1 nm due to the objective lens system in electron microscopes.
What will be the de Broglie wavelength of an electron having a kinetic energy of 500 eV?
What is the DeBroglie wavelength of a 500 eV electron in an electron microscope? E = hc/λ or λ = hc/E = (6.626 x 10-34 Js)(2.99 x 108 m/s)/(8.1 x 10-17 J) λ = 2.44 x 10-9 m = 2.44 nm, which is about 5 times too big! Wavelength = _____________________.
