A moving electron has numerical relation `lambda=h`. Then,

According to de-Broglie hypothesis, the wavelength associated with moving electron of mass 'm' is 'lambda_(e)' . Using mass energy relation and Planck's quantum theory, the wavelength associated with photon is 'lambda_(p)' . If the energy (E) of electron and photonm is same, then relation between lambda_e and 'lambda_(p)' is

Numericals related to First law

de-Broglie proposed the dual nature of electron and put forward his wave concept. The wave length of electron in an orbit was given by lambda =h/(mv) The wavelength of moving electron in 3^(rd) Bohr orbit of H-atom is

The de Broglie wavelength of an electron moving in a circular orbit is lambda . The minimum radius of orbit is :

The de Broglie wavelength of an electron moving in a circular orbit is lambda . The minimum radius of orbit is :

A proton and an electron initially at rest are accelerated by the same potential difference. Assuming that a proton is 2000 times heavier than an electron, what will be the relation between the de Broglie wavelength of the proton (lambda_p) and that of electron (lambda_e)

If a light of wavelght lambda hits moving electron the uncertainty in measurement of its position will be

If a light of wavelength lambda hits moving electron the uncertainty in measurement of its position will be

A proton and an electron initially at rest are accelerated by the same potential difference. Assuming that a proton is 2000 times heavier than an' electron, what will be the relation between the de Broglie wavelength of the proton (lambda_(p)) and that of electron (lambda_(e)) ?
