How are colors produced and why?
Colours are produced when electromagnetic radiation is emitted. The precise colour will depend on the wavelength of the radiation.
What is light produced by?
A filament is heated by an electric current and photons are emitted.
What is light produced?
A filament is heated by an electric current and photons are emitted.
Why is mercury used in streetlights?
The light emitted by excited mercury gas is predominantly in the visible spectrum and as a light source is relatively efficient.
What type of energy is produced when a heated chemical glows?
Photons are emitted (light energy) and infrared energy.
When potassium-39 is bombarded by neutrons chlorine-36 is produced what other particles are emitted?
An Alpha particle
When a strontium compound is heated in a flame red light is produced When a barium compound is heated in a flame yellow-green light is produced Explain why these colors are emitted?
Yes
Can you list three kinds of changes that indicate a chemical reaction has taken place?
Some signs that a chemical change has taken place is that a gas can be produced, the temperature can change, and a substance disappears. Other signs are that a solid is formed, the color changes, and a new odor is produced.
How is the light of an emission spectrum of an element produced?
Basically, energy is emitted when an electron falls from a higher energy level to a lower energy level. Such energy is emitted as electromagnetic waves, which in certain cases can be visible light.
What is open cycle and closed cycle?
In an open cycle gas turbine, the gases that are produced by combustion go directly into the atmosphere, though the heat produced can sometimes be reclaimed. In a closed cycle gas turbine, the gases produced are reused and are not emitted into the atmosphere.
Spectral lines produced from the radiant energy emitted from excited atoms are thought to be due to the movements of electrons?
From higher to lower energy levels
What type of spectrum is produced when the light emitted directly from a hot dense object passes through a prism?
Its called atomic spectrum
