Text Solution

Verified by Experts
The correct answer is:
A
Step 1: Understand the context of the question. The problem discusses the splitting of spectral lines when exposed to an external electric or magnetic field.
Step 2: Identify the terms provided in the options:
  • Zeeman's effect: It refers to the phenomenon where spectral lines are split into multiple components in the presence of a magnetic field.
  • Bohr's effect: This typically relates to hemoglobin function, not line splitting.
  • Heisenberg's effect: This usually refers to uncertainty principles in quantum mechanics.
  • Magnetic effect: This is a general term and does not specifically denote line splitting.
Step 3: Since Zeeman's effect is the specific phenomenon of line splitting due to magnetic fields, it is the correct answer.
Therefore, the correct answer is A.
