The wavelength of the photon emitted can be calculated using the Rydberg formula: 1/wavelength = R(1/n1^2 - 1/n2^2), where R is the Rydberg constant, n1 is the initial energy level (2 in this case), and n2 is the final energy level (1 in this case). Plugging in the values gives the wavelength of the photon emitted.

What is the energy of a photon emitted with a wavelength of 518 mp?

The energy of a photon can be calculated using the equation E = hc/λ, where h is Planck's constant, c is the speed of light, and λ is the wavelength. Plugging in the values, the energy of a photon with a wavelength of 518 nm is approximately 3.82 eV.


What is the energy of a photon emitted with wavelength of 518 nm?

3.84 x 10-19 joules.


How does photon energy change with wavelength?

The energy of a photon is inversely proportional to its wavelength. This means that as the wavelength increases, the energy of the photon decreases. Conversely, as the wavelength decreases, the energy of the photon increases.


When an electron in atom changes energy states a photon is emitted If the photon has a wavelength of 550 nm how did the energy of the electron change?

The energy of the electron decreased as it moved to a lower energy state, emitting a photon with a wavelength of 550 nm. This decrease in energy corresponds to the difference in energy levels between the initial and final states of the electron transition. The energy of the photon is inversely proportional to its wavelength, so a longer wavelength photon corresponds to lower energy.


What is the wavelength of a photon whose energy is twice that of a photon with a 580 nm wavelength?

Since the energy of a photon is inversely proportional to its wavelength, for a photon with double the energy of a 580 nm photon, its wavelength would be half that of the 580 nm photon. Therefore, the wavelength of the photon with twice the energy would be 290 nm.


What effect would lower wavelength have on the emitted photoelectrons?

Lowering the wavelength of incident light increases its energy, which in turn can increase the kinetic energy of the emitted photoelectrons. This is in line with the photon energy equation E=hf, where E is energy, h is Planck's constant, and f is frequency (which is inversely proportional to wavelength).


What determines which photon an atom can absorb or emit?

An atom can absorb or emit photons based on its energy levels and electronic structure. When a photon energy matches the energy difference between two energy levels in the atom, it can be absorbed or emitted. This is governed by the quantized nature of energy levels in atoms.


What occurs as the wavelength of a photon increases?

As the wavelength of a photon increases, its frequency decreases. This means the energy of the photon decreases as well, since photon energy is inversely proportional to its wavelength.


What is the energy of a photon emitted with a waveleng of NM?

The energy of a photon can be calculated using the equation E = hc/λ, where E is the energy, h is Planck's constant (6.626 x 10^-34 J s), c is the speed of light (3 x 10^8 m/s), and λ is the wavelength. Plugging in the values given, the energy of a photon emitted with a wavelength of 1 nm is approximately 2 x 10^-16 J.


A photon has an energy of 1.94 1013 J What is the photon's wavelength?

To find the wavelength of the photon, you can use the formula: wavelength = (Planck's constant) / (photon energy). Substituting the values, the wavelength is approximately 1.024 x 10^-7 meters.


Does photon of 420nm contain more energy than a photon of 790nm?

Yes, a photon with a wavelength of 420nm contains more energy than a photon with a wavelength of 790nm. This is because energy is inversely proportional to wavelength, meaning shorter wavelengths have higher energy.


How does the energy of a photon compare in difference in energy levels of the atom from which it is emitted?

The energy of a photon emitted from an atom is determined by the energy difference between the initial and final energy levels of the atom. The energy of the photon is directly proportional to this difference in energy levels. If the energy levels are farther apart, the emitted photon will have higher energy, whereas if the levels are closer together, the photon will have lower energy.
