Monochromatic light of wavelength 632.8 nm is produced by a helium-neon laser. The power emitted is 9.42 mW. How fast does a hydrogen atom have to travel in order to have to have the same momentum as that of the photon ?
The numbering of carbon atoms is done in such a way that the substituted carbon atoms have the lowest possible numbers
Atoms of different elements having same mass number but different atomic numbers are called
Atoms of the same element having same atomic number but different mass number are called
