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 .

Options

A. If both the assertion and reason are true and reason is correct explanation of the assertion .
B. If both the assertion and reason are true but reason is not a correct explanation of the assertion .
C. If the assertion is true but the reason is false.
D. If both assertion and reason are false.

Answer

C

Explanation

The wavelength of the line can be calculated by the Ritz formual :
`(1)/(lambda)=R"((1)/(n_(1)^(2))-(1)/(n_(2)^(2)))`,R=Rydberg constant
Therefore , for calculating highest wavelength in Balmer series ` (n_(1)=2),n_(2)` should be 3,4,5 .
