Question

What is the wavelength of the photon emitted as the electron in the hydrogen atom transitions from the 3rd to 2nd level? What is the frequency of the photon and what is the energy carried by the photon?

got -6606 A for the first one and I'm not sure if I'm doing it right

Answer #1

a. what is the energy of the emitted photon if an electron in
the hydrogen atom makes a transition from the n=7 state to the n=2
state?
b. Now, Imagine there is a photon with the same wavelength. What
is the speed of this photon?

What is the wavelength of light (in m) emitted by a hydrogen
atom when an electron relaxes from the 5 energy level to the 3
energy level?

A hydrogen atom transitions from the n = 6 excited state to the
n = 3 excited state, emitting a photon.
a) What is the energy, in electron volts, of the electron in the
n = 6 state? How far from the nucleus is the electron?
b) What is the energy, in electron volts, of the photon emitted
by the hydrogen atom? What is the wavelength of this photon?
c) How many different possible photons could the n = 6...

The best answer for the wavelength of light emitted when an
electron transitions from the fourth energy level to the first
energy level in a hydrogen atom is:
a. 97.2 nm
b 972 nm
c. 9.72 nm
d. 9720 nm
e. .972 nm

A photon is incident on a hydrogen atom. The photon
moves the electron from an n = 5 energy level to an n = 10 energy
level.
A: Is this an absorption or emission process? Choose
one.
B: What is the wavelength, in nanometers, of the
incident photon?

Consider the following four transitions in a hydrogen atom.
(i) ni = 6, nf = 9 (ii) ni = 6, nf = 12 (iii) ni = 10, nf = 12
(iv) ni = 9, nf = 6
(a) Give the wavelength of the longest-wavelength photon that
can be emitted or absorbed by these transitions. m
(b) Give the wavelength of the shortest-wavelength photon that
can be emitted or absorbed by these transitions. m
(c) For which of these transitions does...

Calculate the energy of the emitted photon as well as the
wavelength and frequency of electromagnetic radiation emitted from
the hydrogen atom when the electron undergoes the transition from n
= 5 to n = 1. In what region of the spectrum does this line
occur?

Q6] A hydrogen atom transitions from the ni = 5 state down to
the ground state. In the process it emits a photo of light. The
photon then strikes a photo-electric material with a work function
of Wo = 7.5eV . a) What is the wavelength of the photon emitted
from the transition of the hydrogen atom? b) What is the kinetic
energy of the electron ejected from the photo-electric
material?
