What is the name of the phenomena in physics and astronomy which involves the splitting of a spectral line into two or more components of slightly different frequency when the light source is placed in a magnetic field?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e Zeeman Effect
1. Zeeman Effect is the effect of splitting of a spectral line into two or more components of slightly different frequency when the light source is placed in a magnetic field.
2. It was first observed in 1896 by the Dutch physicist Pieter Zeeman as a broadening of the yellow D-lines of sodium in a flame held between strong magnetic poles.

| Raman Effect | Raman effect is the inelastic scattering of photons by matter, meaning that there is an exchange of energy and a change in the light's direction. |
| Alpenglow Effect |
It is an optical phenomenon that appears as a horizontal reddish glow near the horizon opposite to the Sun when the solar disk is just below the horizon. This effect is easily visible when mountains are illuminated, but can also be seen when clouds are lit through backscatter. |
