Assertion : For Balmer series of hydrogen spectrum, the value n₁=2 and n₂=3,4,5 . Reason: The value of n for a line in Balmer series of hydrogen spectrum having the highest wavelength is 4 and 6 .

Options

  1. AIf both the assertion and reason are true and reason is a correct explanation of the assertion.
  2. BIf both assertion and reason are true but assertion is not a correct explanation of the assertion.
  3. CIf the assertion is true but the reason is false.
  4. DIf both assertion and reason are false.

Correct answer

C. If the assertion is true but the reason is false.

Step-by-step solution

The wavelength of the line can be calculated by the Ritz formula : 1 =R ( 1 n₁^2 - 1 n₂ ^2 ), R= Rydberg constant Therefore, for calculating highest wavelength in Balmer series (n₁=2 ), n₂ should be 3 .
