Question

The wavelength of first line of Lyman series is lambda the wavelength of the second line of Lyman series is​

Answer 1

Answer:

Hey mate here is your answer.//

Explanation:

The wavelength of the first line of Lyman series is lambda the wavelength of the seconf line of Lyman series is Hydrogen Spectra.

1/ λ = R[1/n₁² - 1/n₂²]

For second line of Lyman series

n₁ = 1 and n₂ = 3

1/λ = R[1/1² - 1/3²]

= 8R/9

λ = 9 / (8R)

= 9 / (8 × 1.097 × 10^7 m^1)

= 102.5 nm

∴ Wavelength of second line of Lyman series is 102.5 nm
