Let r, v, E be the radius of orbit, speed of electron and total energy of electron respectively in H-atom. Which of the following quantities according to Bohr theory, is proportional to the quantum number n ?
If R is the Rydberg constant in cm-1, then hydrogen atom does not emit any radiation of wavelength in the range of
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)?
To which of the following the angular velocity of the electron in the n-th Bohr orbit is proportional?
