SUMMARY
The discussion focuses on calculating the de Broglie wavelength of an electron with a speed of 2.2 x 106 m/s. The participant correctly applies the formula for momentum (P = MV) using the mass of the electron (9.11 x 10-31 kg) to find the momentum as 2 x 10-24 kg·m/s. Subsequently, they use the de Broglie wavelength formula (λ = h/p) with Planck's constant (h = 6.62 x 10-34 J·s) to calculate the wavelength as 3.33 x 10-10 m, which is confirmed as a typical result.
