Use Rydbuz equation to calculate the

Question

wavelength of the third line in the paschen
series of the hydrogen spectrum.give ur
answer in Nm.

RH=2.18 * 10^-18j,

H=6.63 * 10^-34J.

Plz help m

Answer 1

Rydberg equation?

1/lambda=R (1/n1^2- 1/n2^2)
N2=infinity
N1=3

solve for lambda

Answer 2

1 / λ = R [(1 / n₁^2) - (1 / n₂^2)]

R = 1.097 x 10⁷ m⁻¹

the starting principle quantum number (n₁) for the Paschen Series is 3

the number (n₂) for the 3rd line is 6
