Assertion : For Balmer series of hydrogen spectrum, the value n_1… - Vidyadip

MCQ

Assertion : For Balmer series of hydrogen spectrum, the value $n_1 = 2$ and $n_2 = 3, 4, 5.$
Reason : The value of $n$ for a line in Balmer series of hydrogen spectrum having the highest wave length is $4$ and $6$.

A
If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.
B
If both Assertion and Reason are correct but Reason is not a correct explanation of the Assertion.
✓
If the Assertion is correct but Reason is incorrect.
D
If both the Assertion and Reason are incorrect.

✓

Answer

Correct option: C.

If the Assertion is correct but Reason is incorrect.

c
The value of $n$ for a line in Balmer series of hydrogen spectrum having the highest wave length will be $n_1 = 2$ and $n_2 = 3$ because this transition will have lowest energy and so highest wavelength.
