Question

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.

(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 correct explanation of A  

(c) A is true but R is false  

(d) A and R are false

Answer 1

Correct option (c) A is true but R is false  

Explanation:

The wave length of the line can be calculated by the Ritz formula :

R-Rydberg constant

Therefore, for calculating highest wavelength in Balmer series (n₁ = 2), n. should be 3.
