Atoms emit energy as light when?
Atoms emit energy as light when electrons move to a lower energy level
What are the five sources of light and heat?
1. The main source is the sun. Even though rocks seem like they emit heat, they really got their heat initially from the sun. 2. Radioactive substances emit their own energy and heat. 3. Warmblooded animals emit heat. However, they make the energy from the food they eat which ultimately came from the sun. 4. Electricity. Electricity can be used to make heat and light. 5. Other stars from other solar systems emit their own light.
Benefits non-conventional sources of energy?
If you mean sources like wind and solar energy, they are renewable because they don't consume fuel which is non-renewable, they don't emit greenhouse gases, and the sources of energy are free.
Why is light from a common lamp or from a candle flame nonpolarized?
Natural light sources and artificial sources emit light with orientations of the electric vector that are random in space and time, thus proving to be nonpolarized.
What happens to the particles of matter when thermal energy is added to it?
When thermal energy is added to particles of matter, it causes the particles to move faster and emit more energy.
Atoms emit energy as light when?
Atoms emit energy as light when electrons move to a lower energy level
Why does light attract heat?
It Doesn't!!! Light sources sometimes emit heat as Infra Red radiation which is part of the electromagnetic spectrum, like visible light, but you can't see it. It Doesn't!!! Light sources sometimes emit heat as Infra Red radiation which is part of the electromagnetic spectrum, like visible light, but you can't see it. Light = Energy = Heat = Can make light?
Does the energy from Sun energise other planets so they can emit light?
No. Planets do not emit light; they can only reflect light from the Sun.
Can a traffic light emit light energy?
Yes. That is why they are called traffic lights.
Why do you know that lithium salts will never emit green light and copper salts will never emit red light?
Because they each have their own level of energy. Green light has more energy than red light.
Why si and ge does not emit light?
energy levels wrong.
Why is light an important tool used in astronomy?
Stars are the sources of light. If they did not emit light, there would be no stars and thus no astronomy.

Why is light from a common lamp nonpolarixed?
Natural light sources and artificial sources emit light with orientations of the electric vector that are random in space and time, thus proving to be nonpolarized.

Would solid matter have to be turned in to light to reach the speed of light?
Matter has mass. Nothing with mass can travel at the speed of light; only massless particles, electromagnetic waves, and gravity waves can. It is possible to turn matter into energy and emit it in the form of electromagnetic radiation such as light. This process occurs during nuclear reactions and when matter and antimatter annihilate one another.
Light energy travels in electromagnetic waves How do electromagnetic waves emit energy?
Through Radiation
