Practice Problem: The Bohr Model and Photon Wavelength

Dave explains a practice problem involving the Bohr model, focusing on calculating the wavelength of a photon that causes an electron transition in a hydrogen atom. The tutorial covers the necessary equations, including the Rydberg formula and Planck's equation, and demonstrates the calculation of energy change and wavelength. Key concepts such as photon absorption, energy levels, and conservation of energy are discussed, providing a comprehensive understanding of the topic.

What is the initial energy level of the electron in the given problem?

• n = 6

• n = 5

• n = 4

• n = 2

Which constant is used to relate the energy of a photon to its frequency?

• Gravitational constant

• Planck's constant

• Boltzmann constant

• Rydberg constant

What is the significance of the Rydberg constant in this problem?

• It is used to determine the energy levels of an electron.

• It is used to find the mass of an electron.

• It is used to calculate the wavelength of a photon.

• It is used to calculate the speed of light.

What is the change in energy of the electron during the transition?

• 3.566 * 10^-20 Joules

• 5.566 * 10^-20 Joules

• 9.566 * 10^-20 Joules

• 7.566 * 10^-20 Joules

How is the energy of the photon related to the change in energy of the electron?

• The energy of the photon is half the change in energy of the electron.

• The energy of the photon is double the change in energy of the electron.

• The energy of the photon is unrelated to the change in energy of the electron.

• The energy of the photon is equal to the change in energy of the electron.

Which formula is used to calculate the wavelength of the photon?

• Lambda = H / (E * C)

• Lambda = E / (HC)

• Lambda = HC / E

• Lambda = C / (E * H)

What is the calculated wavelength of the photon involved in the transition?

• 2.626 * 10^-6 meters

• 3.626 * 10^-6 meters

• 1.626 * 10^-6 meters

• 4.626 * 10^-6 meters
