What is the energy of a photon emitted with wavelength of 518 nm?
3.84 x 10-19 joules.
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).
The light bearing packet of energy emitted by an electron is called a?
A packet of light energy is called a photon.
What is the energy of a photon emitted with a wave length of 654 nm?
The energy of a photon can be calculated using the equation E = hc/λ, where E is the energy of the photon, h is Planck's constant (6.626 x 10^-34 J*s), c is the speed of light (3.0 x 10^8 m/s), and λ is the wavelength of the photon. Plugging in the values, the energy of a photon emitted with a wavelength of 654 nm (or 6.54 x 10^-7 m) is approximately 3.02 x 10^-19 J.
When an electron drops from a higher energy state to a lower energy state?
When an electron drops from a higher energy state to a lower energy state, it emits electromagnetic radiation in the form of a photon. This process is known as atomic emission, and the energy of the emitted photon corresponds to the energy difference between the two electron states.
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.
How can we calculate the wavelength of the photon emitted in a given scenario?
To calculate the wavelength of a photon emitted in a given scenario, you can use the formula: wavelength speed of light / frequency of the photon. The speed of light is approximately 3.00 x 108 meters per second. The frequency of the photon can be determined from the energy of the photon using the equation E hf, where E is the energy of the photon, h is Planck's constant (6.63 x 10-34 joule seconds), and f is the frequency of the photon. Once you have the frequency, you can plug it into the formula to find the wavelength.
What is the energy in cm-1 of the photon emitted during the transition of an electron in a hydrogen atom from the n3 to n2 energy level?
The energy of the photon emitted during the transition of an electron in a hydrogen atom from the n3 to n2 energy level is approximately 364.5 cm-1.
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 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 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.
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.
