MCQ
Assertion (A): Splitting of the spectral lines in the presence of a magnetic field is known as the Stark effect.
Reason (R): The line spectrum is simplest for the hydrogen atoms.
  • A
    Both A and R are true and R is the correct explanation of A.
  • B
    Both A and R are true but R is not the correct explanation of A.
  • C
    A is true but R is false.
  • A is false but R is true.

Answer

Correct option: D.
A is false but R is true.
(d) A is false but R is true.
Explanation: Splitting of the spectral lines in the presence of a magnetic field is known as the Zeeman effect and in an electric field is known as the Stark effect. The splitting of spectral lines is due to different orientations which the orbitals can have in the presence of the magnetic field.
