Question

A successful feature of Bohr Model was that his theory accounted for the Rydberg equation, which made it possible to calculate wavelengths of the hydrogen spectral lines. Using the Rydberg equation, calculate the wavelength (in nm) of a spectral line produced in the hydrogen spectrum, when an electron falls from the 4th energy level to the 2nd energy level. Which region of the electromagnetic spectrum does this spectral line belong to? [Note: Rydberg constant, RH = 109,678,00 m-1]

Answer 1

Answer:

we know 1/$=RH*(1/n1^2 -1/n2^2) where $=wavelength (I wrote it for the easy understanding)

so given

n1=4

n2=2

so 1/$=109678 (1/4^2 -1/2^2)

by calculating it we get the answer I don't know the answer right or wrong lol
