Consider an electron with a (non-relativistic) kinetic energy of 1 eV.(i) What is the electron speed in m/s? What is the de Broglie wavelength of the electron?(ii) Consider a beam of 1 eV electrons incident on a pair of very thin slits, separated by adistance d, with an interference pattern seen on a screen 2 m beyond the slits. Find thevalue of d such that the position of the first off-center bright fringe of the pattern islocated 0.5mm from the center of the pattern.

can you solve C please
In the classical limit calculate the wavelength corresponding to an electron with the energy of 99 kev (kiloelectronvolt). Give your answer in Angstrom (10-10 1.6x10-10 m, then write 1.6 as your answer). This m, for example, if the answer is should give you a good idea why one can use a crystal lattice with an average interatomic distance of around 1010 m to observe electron diffraction.

i need the answer quickly
I need help with this question. Originally I got 3 degrees for the answer, but it appears that this is incorrect and I don't know what went wrong. Here is the question: Electrons with an energy of 0.610 eV are incident on a double slit in which the two slits are separated by 60.0 nm. Electron speed is 4.63e+05 m/s and the de Broglis wavelength of the electrons is 1.57 nm. What is the angle between the two second-order maxima in the resulting interference pattern. I really appreciate the help!
