Question

Calculate the frequency and the wavelength of the radiation in nanometers emitted when an electron in the hydrogen atom jumps from third orbit to the ground state. In which region of the electromagnetic spectrum will this line lie ? (Rydberg constant = 109, 677 )​

Answer 1

Answer:

Calculate the frequency and the wavelength of the radiation in nanometers emitted when an electron in the hydrogen atom jumps from third orbit to the ground state. In which region of the electromagnetic spectrum will this line lie? (Rydberg constant = 109,677 cm^(-1) )

Answer 2

Answer:

Answer

Correct option is

B

Visible region

Let,

wave number =R
