Where does all light originate?
Light is a visual manifestation of energy; resonation of particles at very high frequencies. Mass can become energy and energy can become mass, according to Einstein's relativity theorem. Imagine two substantial masses colliding at high speed. This would release enough energy to produce visible ligt.
Why do you see colors in flame tests?
When an atom is in the flame, an electron in the outer shell of that atom receives energy from the flame and jumps up to a higher shell position. This electron then falls back to is original position and in doing so emits a photon of light of a specific energy. You see this light as a color. Atoms from different elements have different numbers of electrons in their electron shells so the photons emitted as these electrons jump back are all of different energy and therefore emit light of a different color. The color of the flame in the flame test therefore helps to identify the element in the flame producing the colored light.
Why is a ladder not a good model for the atom?
a ladder could be used to interpret the emission of light when an electron gets excited, moves to a higher rung, and then falls to a lower or bottom rung. otherwise, it shows nothing of how the atom is constructed, the number of protons, neutrons, electrons, etc
The release of light energy by particles of matter that have absorbed extra energy is called?
Light Emission. Re-emission phosphorescence and fluorescence are examples of processes that cause light to be emitted. When the electrons of an atom are excited to a higher energy level, they emit a quantum of light (photon) as the electron falls back to a lower energy level.
What are some positives about hydroelectric energy?
They don't pollute, its renewable, you can get alot of it, especially Niagara falls, clean energy
What happens to the energy of the electron as it falls down the electron transport chain?
pie
Why is a shorter wavelength of light emitted when an electron falls from n equals 4 to n equals 1 than when an electron falls from n equals 2 to n equals 1?
Shorter wavelength = more energy. The farther the electron falls, the more energy that will be emitted.
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.
If an electron is in an excited state it must lose energy when it falls to a lower state. What happens to the energy that is lost?
The energy that is lost when an electron falls to a lower state is emitted as a photon of light. This process is known as photon emission, and the energy of the emitted photon corresponds to the energy difference between the initial and final states of the electron.
Emission of light from an atoms occurs when an electron?
falls from a higher energy state to a lower energy state.
If an electron gun electron is moved with electric potential of 9000 volt.then What will be the energy of electron in electron volt?
The energy of the electron in electron volts can be calculated by using the formula E (in electron volts) = V (volts) * e, where "e" is the elementary charge of an electron (approximately 1.6 x 10^-19 coulombs). Plugging in the values, E = 9000 V * 1.6 x 10^-19 C ≈ 1.44 x 10^-15 electron volts.
Why electron jumps from ground state to exicted state?
An electron jumps from the ground state to an excited state when it absorbs energy, typically in the form of a photon. This causes the electron to move to a higher energy level, creating an excited state. When the electron later falls back to the ground state, it releases the absorbed energy in the form of a photon.
Emissin of light from an atom occurs when an electron what?
Lots of wrong answers out there, tested this on school, the answer is: Drops from a higher to a lower energy level
What electron transition represents a gain of energy?
All transitions in which electrons move from a lower to a higher level require a gain of energy. example: 2nd to 3rd shell
What has to happen before you can move to a new energy level in the electron cloud?
An electron must absorb or release a specific amount of energy, typically in the form of a photon, to move to a new energy level in the electron cloud. This process is known as electron excitation or de-excitation.
What happens when an electron falls back an energy level?
When an electron falls back an energy level, it releases energy in the form of electromagnetic radiation (such as light). This process is known as electron transition or atomic emission, and the energy of the emitted light corresponds to the energy difference between the two energy levels involved.
Why it is considered as the energy of an electron is quantised?
Electrons orbit the nucleus of an atom in specific orbitals, a specific distance from the nucleus of the atom. A specific quanta of energy will knock the electron into a higher orbital. When the electron falls back into the lower orbital, it will give off that same specific quanta of energy. That is why lasers work.
