Matter emits light for several reasons:
1) When an electron surrounding a nucleus goes from one state to another at a lower energy, the most efficient way for energy to be conserved is for the atom to emit a photon -- ie, light. This is why a neon light gives off red light.
2) When electrons are actively vibrating due to the motions of the atoms they are connected to, Maxwell's Laws show that they will give off EM vibrations -- ie, light. This is why a fire is bright.
3) When free electrons are rapidly buzzing around, interacting with other charged particles, their accelerations due to these interactions also result in EM vibrations. This is one reason our Sun is glowing.
What else can I help you with?
When a meteoroid enters Earth's atmosphere it produces a streak of light called a?
The streak of light created by a meteoroid entering the Earth's atmosphere is called a meteor. A meteorite is the remains of a meteoroid that did not vaporize after entering the Earth's atmosphere.
Is light and sound is matter?
Light is not considered matter as it consists of massless particles called photons. Sound, on the other hand, is a form of energy that propagates through matter as mechanical waves, so it is not considered matter in itself.
When absorbed light energy is released by matter it is called what?
Example for light energy is absorbed or released, Heat is released and absorbed, electrical energy absorbed or released...
Is flame considered a matter?
Flame cannot be considred as matter exactly. It is combination of light and heat, which originate due to the combustion of matter at that point.
What kind of Matter that light can pass through but is scattered?
Light can pass through matter that is transparent, but still be scattered if the matter is not completely uniform or smooth. Examples include frosted glass, wax paper, and frosted plastics.
What happens when light enters polarizing filter?
what happens when light enters a polorizing filter?
What happens to both pupils when light enters?
Pupils "constrict" when light enters, and "dilate "when the lighting dims
What happens to the intensity of light when it enters a dnser medium?
There's no reason to expect that the intensity of light must necessarily change when it enters a different medium.
What happens when matter inters a black hole?
well, i am a child but this is so easy 4 me! matter gets crushed and destroyed when it enters a black hole.any thing that enters a black whole never gets out. matter also gets stretched out when it enters a black hole.
What is happens when light is refracted by matter?
the light bends.
What happens to the speed of the sound and the light as it enters the plastic?
Depends on the type of plastic.
What happens as light enters a medium and its speed increases?
It reflects a rainbow pattern
What happens after the light enters the prism?
When light enters a prism, it refracts into different colors due to the varying speeds of light in different mediums. This separation of colors is known as dispersion and creates a rainbow spectrum.
Why does light slow when it enters a medium or matter?
When light enters a medium, it interacts with the atoms of the medium, causing the light to be absorbed and re-emitted. This process introduces a delay, resulting in a slower speed of light in that medium compared to a vacuum.
What happens to the direction of light when matter reflects light?
the light changes direction.
What happens if anti matter enters a black hole?
Probably the mass of the black hole would increase, just as when normal matter falls in.
What happens to the speed of light as it enters a different meduim?
It changes, in accordance with the optical density of the medium.
