List of top Physics Questions on Bohr’s Model for Hydrogen Atom asked in AP EAMCET

In case of diffraction, if \( a \) is a slit width and \( \lambda \) is the wavelength of the incident light, then the required condition for diffraction to take place is:

The speed of the electron in a hydrogen atom in the \( n = 3 \) level is:

Energy of a stationary electron in the hydrogen atom is
\[ E=-\frac{13.6}{n^2}\ \text{eV} \] then the energies required to excite the electron in hydrogen atom to (a) its second excited state and (b) ionized state respectively are
