Question

For the hydrogen spectrum,the wavelength in Balmer series is given by $\frac{1}{λ}$=R($\frac{1}{n_{1}^{2}}$-$\frac{1}{n_{2}^{2}}$) where λ= wavelength and R is Rydberg constant. What are the values of n1 and n2,for the longest wavelength in the Balmer series?

• A. n1=2,n2=3
• B. n1=2,n2=4
• C. n1=1,n2=2
• D. n1=2,n2=∞
• E. n1=3,n2=∞

Answer 1

Answer: (A)

n1=2,n2=3

Answer 2

The correct answer is (A): n1=2,n2=3
