Heisenberg uncertainty principle can be applied to all the objects and for macroscopic objects the uncertainty is extremely large

Azimuthal Quantum number explains about spatial orientation of orbital

Photon has momentum as well as wavelength, but electrons do not have momentum and wavelength

In photoelectric effect if frequency $\mathrm{v}>v_o$, then photoelectrons are ejected with certain kinetic energy

greater than the energy of the incident photon

smaller than the energy of the incident photon

same as that of the incident photon

proportional to the intensity of the incident photon
