Webb25 dec. 2024 · Let's find the de Broglie wavelength of an electron traveling at 1% of the speed of light. The mass of an electron is 1 me, or 9.10938356*10-31 kg; The speed of this electron is. Multiplying the mass and speed, we obtain the momentum: p = mv = 2.7309245 × 10-24 kg·m/s; Dividing the Planck constant by p, we obtain the de Broglie wavelength: Webb3 feb. 2010 · A proton is traveling with a speed of v = 2.990x10 8 m/s. Calculate the (relativistically correct) value of the kinetic energy for this proton. Assume that the speed of light is c = 3.000 x 10 8 m/s and that the mass of the proton is 1.673 x 10-27 kg. Note: Do your calculations to 4 significant figures.
WebbSo each electron gains kinetic energy equal to the amount of energy transferred electrically. The electron starts from rest (near enough) so the kinetic energy gained is given by ½ mv 2 where m is its mass and v is its speed. So we can say that: ½ mv 2 = eV. The mass of the electron is m = 9 × 10-31 kg. The electronic charge is e = 1.6 × 10 ... WebbAs particles travel through the Universe, there’s a speed limit to how fast they’re allowed to go. No, not the speed of light: below it.
WebbIn particular, suppose a particle travels from a region of strong magnetic field to a region of weaker field, then back to a region of stronger field. The particle may reflect back before entering the stronger magnetic field region.
