What causes photons to be emitted from excited atoms?
The energy difference, between two energy levels, is emitted as a photon, when the electron "falls down" to a lower energy level.
Can free electron absorb photon?
a free electron may absorb a photon only if its parity changes
An atom can be excited if it?
thermal agitation, electron impact, and photon impact
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 difference between excited hydrogen atom and any other atom?
Hydrogen atom = 1 proton 1 electron Hydrogen's 1 electron occupies the lowest energy level, 1s orbital. The atom is therefore in its "ground state". When a photon of correct frequency "collides" with a electron in hydrogen's 1s orbital the energy contained in the photon is transferred to the electron. The electron then gets added energy, so it is at a higher energy state. When it reaches this higher energy state the electron jumps to the next energy level and there it starts its new orbit. Hydrogen atom is now "excited" For any other atoms it is the same thing because all atoms can undergo excitation. The only difference between hydrogen's 1 electron and other atom's many electrons is WHICH ELECTRON will be "excited"
When a photon is emmit out from the atom its color is same as the atom color?
No. The color of the electron depends on the energy difference between the levels from/to which it is changing.
What causes photons to be emitted from excited atoms?
The energy difference, between two energy levels, is emitted as a photon, when the electron "falls down" to a lower energy level.
When an electron drops to a lower energy level what is the energy of the photon released?
The energy of the photon is the same as the energy lost by the electron
Can free electron absorb photon?
a free electron may absorb a photon only if its parity changes
What is the difference between tata photon whiz and tata photon plus?
tata photon plus is ratan tata and Javed Siddiqui is houner of PHoton whiz..............
Why is the energy of a photon greater than that of an electron?
It does not. A photon has no rest mass an electron has mass and therefore more energy
When an electron drops back down toa lower level it gives off a single flash of light called?
a photon (btw --- doesn't have to be 'light'; could be a photon of radio, microwave, infrared, ultraviolet, heat, x-ray, etc. Depends on the atom the electron is in, and the difference between the level it fell from and the level it wound up at.)
What is the difference between linear and non linear optics?
In the case of linear optical transitions, an electron absorbs a photon from the incoming light and makes a transition to the next higher unoccupied allowed state. When this electron relaxes it emits a photon of frequency less than or equal to the frequency of the incident light (Figure 1.3a). SHG on the other hand is a two-photon process where this excited electron absorbs another photon of same frequency and makes a transition to reach another allowed state at higher energy. This electron when falling back to its original 39 state emits a photon of a frequency which is two times that of the incident light (Figure 1.3b). This results in the frequency doubling in the output.
When an electron drops to a lower energy level what is the energy of a photon released?
The energy of the photon is the same as the energy lost by the electron
Is an electron and photon the same thing. It seems like my book interchanges them for one another. I'm confused?
No. The electron is not a photon. An electron is a charged particle of matter. A photon is a unit of "energy-time" designated by Planck's Constant h.
An atom can be excited if it?
thermal agitation, electron impact, and photon impact
The light bearing packet of energy emitted by an electron is called a?
A packet of light energy is called a photon.
