Question

What is the frequency of the limiting line of the lyman series?

Answer 1

Answer:

The wavelength of limiting line of Lyman series is 911 A˚.

Answer 2

$waveform = 109678 * (1/n1^2 - 1/n2^2 )$:

here , lyman series has n1 = 1

also limiting line means , n2 = infinity

substituting , wavenumber = 109678 * (1)

wavenumber = 10967800 /m

we know c/λ = υ

since 1/λ = wavenumber

c * wavenumber =  υ

3 * 10^8 * 10967800 = 32904 * 10^10

= 3.29 * 10^14 hz //
