Question

1. An election of mass 9.11x10 3 kg moves at nearly
the speed of light. Using
a velocity of 3.00 x 10 mls,
calculate the wavelength of the electron.​

Answer 1

Answer:Multiplying the mass and speed, we obtain the momentum of the particle: p = mv = 2.7309245 × 10-24 kg·m/s . If we divide the Planck constant by the momentum, we will obtain the de Broglie wavelength: h/p = 6.6261 × 10-34 / 2.7309245 × 10-24 = 2.426 × 10-10 m .
