Question

Splitting of spectral lines in electric field is called stark effect.

• A. True
• B. False

Answer 1

The correct option is A True

1. The splitting of atomic spectral lines as a result of an externally applied electric field was discovered by Stark and is called the Stark effect.

2. As the splitting of a line of the helium spectrum shows, the splitting is not symmetric like that of the Zeeman effect.
