Question

The relation between `lambda_(1)=` wavelength of series limit of Lyman series ,`lambda_(2)=`the wavelength of the series limit of Balmer sereis & `lambda_(3)=` the wavelength of first line of Lyman series:
A. `lambda_(1)=lambda_(2)+lambda_(3)`
B. `lambda_(3)=lambda_(1)+lambda_(2)`
C. `lambda_(2)=lambda_(3)-lambda_(1)`
D. none of these

Answer 1

Correct Answer - D
`K/lambda_(1)=E^(oo)-E_(1)"and" K/lambda_(2)=E_(oo)-E_(2)`
` k/lambda_(3)=E_(2)-E_(1)Rightarrow 1/lambda_(1)-1/lambda_(2)=1/lambda_(3)`
