i ) Electrons in an atom revolve around the nucleus in circular orbits just as the planets revolve round the sun.ii) The electrons revolve only in certain permitted orbits called ‘stationary orbits' and do not radiate energy while in such orbits.iii) Whenever an electron jumps from one stationary orbit to another, absorption or emission of energy takes place. This theory could explain the spectral lines emitted by different elements.
A quarter of a wavelength is equal to how many degrees of phase? A quarter of wavelength is equaivalent to 90 degrees of phase.
When two rays of same frequency, similar wavelength, and similar speed moves in the same direction, their superimposition gives result in the interference. Due to interference the
