SUMMARY

The discussion centers on the definition of an electron's wavelength, represented by the formula λ = h / (mv), where λ is the wavelength, h is Planck's constant, m is the rest mass of the electron, and v is the speed of the electron. Participants confirm that the electron possesses mass, specifically its rest mass of 9.109382 x 10-31 kg, which contributes to its energy. The conversation emphasizes the clarity needed in defining the properties of electrons, particularly regarding their mass.

PREREQUISITES
  • Understanding of quantum mechanics concepts

Given:
[tex]\lambda = h / (mv)[/tex], whehere lambda is the wavelength of electron, h Planck's constant, m the rest mass of electron and v the speed of electron.

Problem:
Does electron has a mass? I know it has a rest mass and thus contain energy. This problem is perhaps a defination problem.

Sure the electron has a mass. (What would make you think otherwise?)
 
electron mass = 9.109382 x 10 to the -31st power (in kg)
