Taking Rydberg's constant `R_(H) = 1.097 xx 10^(7)m` first and second wavelength of Balmer series in hydrogen spectrum is

A

3000 Å

B

2960 Å

C

4280 Å

D

4863 Å

Text Solution

Verified by Experts

The correct Answer is:
D
`1/ lamda = R [(1)/( n_(1)^(2)) - (1)/(n_(2)^(2))]`
for second wavelength `n_1 =-2 ,n_2 =4implies lamda_2 = 4861 Å`
