Splitting of spectral lines in an electric field is called
a) Zeeman effect
b) Shielding effect
c) Compton effect
d) Stark effect
Answered by admin @
The correct Option is D: Stark Effect.
Splitting up of spectral lines in presence of electric field is Called as Stark effect.
Discovery of this effect contributed importantly to the development of quantum theory .
This effect was discovered by German physicist Johannnes stark , who discovered it in 1913 and he was awarded with noble prize in the year 1919.At the same time it was discovered by Italian Physicist Antonino Lo surdo. and hence in Italy it is called as Stark-Lo surdo effect.
Stark effect can lead to splitting of degenerate energy levels.
