If wavelength of photon is $$2.2 \times 10^{-11} \mathrm{~m}$$ and $$h=6.6 \times 10^{-34} \mathrm{~J} \mathrm{~s}$$, then momentum of photon

The number of angular and radial nodes in $$3 p$$ orbital respectively are

With regard to photoelectric effect, identify the correct statement among the following.

Two particle $$A$$ and $$B$$ are in motion. If the wavelength associated with '$$A$$' is $$33.33 \mathrm{~nm}$$, the wavelength associated with '$$B$$' whose momentum is $$\frac{1}{3} \mathrm{rd}$$ of '$$A$$' is
