Why spontaneous emission is incoherent?
During spontaneous emission, photons are emitted randomly and hence they will not in phase with each other. such light is irregular and mixed of different frequencies,direction and duration.therefore the beam of light emitted is incoherent.sudhir tiwari.sharda university
What kind of light is emitted by growing lights?
The light that is emitted by growing lights is a light that can closely mimic that light and warmth of the sun. These lights are considered HID lights and emit a more intense light than a florescent light.
What is infrared light emitted by?
the surface of the atmoshere.
How does the frequency of re-emitted light in a transparent material compare with the frequency of the light that stimulates its re-emission?
The frequency of emitted light in a transparent object is the same as light that stimulates its re-emission.
What form of energy is emitted?
light,heat,sound
What are the different forms of emitted light called?
fluorescence
Is UV light emitted from all lasers?
No, most lasers emit light at a different frequency than UV.
What are the three major forms of emitted radiation?
The three major forms of emitted ionizing radiation are Alpha, Beta and Gamma.
Why do you are there different colors emitted?
There different colors emitted
Why do you think are there different color emitted?
There different colors emitted
What type of radiation is emitted when polonium 212 forms lead 208?
In this case alpha particles are emitted.
Why do you see color when you burn a metallic salt?
During the burning process, electrones shift between different energy levels. Returning from a higher to a lower energy level, electromagnetic waves (light) are emitted. Depending on what substance was burned, waves of different length are emitted, i.e. light of different color is radiated.
How do speed of different forms of light compare?
How many different forms of light do you have ? ? The speed of all wavelengths of electromagnetic radiation is the same, at least in vacuum.

When does lighting occur?
Light is actually photon particles that stem from many different physical processes. For example the sun emits light through radiation stemming from its hot surface. This light is being emitted in order to "cool" the sun. Other forms of light stem purely from electron de-excitation, in which a characteristic light particle is emitted from an atom as an electron in an outer electron state (higher energy) returns to a inner electron state (lower energy).
Why do different elements emits different colored lights when they are subjected to flame?
When the element is subjected to flame, the electrons are in a high energy state. When they come back down to a stable state energy is released in the form of light. The color emitted depends on the amount of energy released.The different colors of the light emitted are caused by the different quantities of electrons losing energy in different elements.
