What else can I help you with?
What were electrons doing when the green light was emitted?
When green light is emitted, electrons are transitioning from higher energy levels to lower energy levels within an atom. This release of energy appears as light in the green wavelength range.
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).
How many electrons are emitted when calcium is flashed with light of wavelength 340 nm and intensity of 50 percent?
The number of electrons emitted when calcium is flashed with light of a certain wavelength and intensity depends on the photoelectric effect, which is related to the energy of the photons hitting the metal. Without the energy of the photons and the work function of calcium, we cannot determine the number of electrons emitted.
What is the difference between emitted light and exciting light?
excited light is the light a chemical absorbs raising it from it's ground state to an excited state. Energy is released as heat and as light. Causes flourescence when chemical returns itself to its ground state. emitted light is the light emitted from the absorbing chemical. When this happens a substance(usually an organic) is emitting a light of longer wavelength after absorbing light of a shorter wavelength.
What happens to atoms and their electrons while the entity emits light?
When atoms emit light, their electrons move to lower energy levels, releasing the excess energy in the form of photons. The photons emitted have a specific wavelength corresponding to the energy difference between the initial and final electron levels. This process is known as emission of light or photon emission.
Atoms emit energy as light when?
they transition from a higher energy state to a lower energy state. This emitted energy appears as light and can vary in wavelength depending on the elements involved and the specific energy levels of the transitions.
What quantum leaps would be associated with the greatest energy of emitted light?
Quantum leaps between energy levels that are farther apart would be associated with the greatest energy of emitted light. This is because energy and wavelength of emitted light are inversely proportional, so larger energy differences result in shorter wavelength (higher energy) light being emitted.
What is the relationship between the light emitted by an atom in the energies of the electrons in the atom?
The more energy levels the electron jumps the more energy the emitted light will have. The more energy you have the shorter wavelength there is.
Why is a shorter wavelength of light emitted when an electron falls from n4 to n1 than when an electron falls from n2 to n1?
When an electron falls from n4 to n1, it releases more energy because it is transitioning between high energy states. This higher energy transition corresponds to a shorter wavelength of light being emitted, according to the energy of the photon being inversely proportional to its wavelength. In contrast, when an electron falls from n2 to n1, the energy released is less, resulting in a longer wavelength of light emitted.
What is the emission wavelength equation used to calculate the specific wavelength of light emitted by a substance?
The emission wavelength equation used to calculate the specific wavelength of light emitted by a substance is c / , where represents the wavelength, c is the speed of light in a vacuum, and is the frequency of the light emitted.
What were electrons doing when the green light was emitted?
When green light is emitted, electrons are transitioning from higher energy levels to lower energy levels within an atom. This release of energy appears as light in the green wavelength range.
Spectral lines produced from the radiant energy emitted from excited atoms are thought to be due to the movements of electrons?
That’s correct. Spectral lines are produced when electrons in atoms move between energy levels. When an electron drops to a lower energy level, it emits a photon of a specific energy corresponding to a specific wavelength of light, creating spectral lines in the emitted light spectrum.
What's the wavelength of the light emitted by the laser?
The wavelength of the light emitted by the laser is typically in the range of 400 to 700 nanometers.
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).
Why calcium turns to red in the flame test?
Because, due to the absorption of heat energy by the calcium atom in the flame. The electrons in the atom get promoted to a higher energy level, and exist in an unstable excited state. As they are unstable and prefer to be at their normal ground state, the extra energy that the electrons absorbed to be promoted in the first place is emitted in the form of a photon, light. The light emitted from the electrons of the calcium atoms will be at a specific wavelength, which is the red light you see emitted from the flame.

One indicator that electrons in atoms are limited to specific energy levels is that?
light emitted from excited atoms occurs only at specific wavelengths
If molybdenum is irradiated with light of a wavelength of 122 nm what is the maximum possible kinetic energy of the emitted electrons?
The maximum kinetic energy of the emitted electrons is calculated using the formula: (E_k = hf - \phi), where (h) is the Planck constant, (f) is the frequency of the light (speed of light/wavelength), and (\phi) is the work function of molybdenum. Given the wavelength, you can calculate the frequency, then use the work function value for molybdenum to find the maximum kinetic energy of the emitted electrons.
