de Broglie wavelength associated with an electron
de Broglie wavelength associated with an electron :- Let an electron is accelerated from rest through a potential difference of V volt, then
Kinetic energy acquired by the electron,
Work done on electron,
If the de Broglie wavelength of the electron is λ , then…
de Broglie wavelength associated with an electron and other charge particles
The energy of a charge particle accelerated through potential difference V is given by,
Hence de Broglie wavelength
Using above formula,
For electron (m = 9.1 × 10-31 kg, q = 1.6 × 10-19 C)
For Proton (m = 1.67 × 10-27 kg, q = 1.6 × 10-19 C)
For Deutron(1H2) (m = 2 × mp = 2 × 1.67 × 10-27 kg, q = 1.6 × 10-19 C)
For alpha particle (m = 4 × mp = 4 × 1.67 × 10-27 kg, q = 2 × 1.6 × 10-19 C)
