Question

Which type of photon is emitted when an electron in a hydrogen atom drops from the n=2 to the n=1?

Answer 1

Answer:

Explanation:

A photon with an energy of 10.2 eV has a wavelength of 1.21 x 10^-7 m, in the ultraviolet part of the spectrum. So when an electron wants to jump from n = 1 to n = 2, it must absorb a photon of ultraviolet light. When an electron drops from n = 2 to n = 1, it emits a photon of ultraviolet light

Answer 2

Hydrogen Spectrum is divided into various series spectrum called as

1) Lyman series

2) Balmer series

3) Paschen series

4) Brackett series

5) Pfund series

When an electron jumps from the state n=2 to n=1 it falls in the Lyman spectrum series. Whenever an electron fall under Layman series it releases the photon in Ultra-violate spectrum.

Therefore, the type of photon emitted in this process is Ultra-violate.
