A ray emitted from a light source is called a light ray. It represents the path that light travels in a straight line from the source in a specific direction.
The material is called a photoemissive material.
Bioluminescence is a source of light similar to phosphorescence. Both types of light emission involve the release of energy in the form of visible light, with phosphorescence having a longer decay time than bioluminescence.
When energy is being given off, it is released in the form of heat, light, or sound depending on the source. When energy is being absorbed, it is taken in and used to perform work or to trigger chemical reactions.
The name given to reflected light is "reflection." This is when light waves bounce off a surface and change direction.
When light bounces off a surface, it undergoes reflection. The angle of incidence (angle at which light strikes the surface) is equal to the angle of reflection (angle at which light bounces off the surface). The Law of Reflection governs this interaction between light and surfaces.
Light and heat are emitted from an energy source...
Solar Energy
Yes. and No. It all depends on the heat given off the source of the artificial light.
The ability for animal life to produce light is called bioluminescence.
You have not given the alternatives, but this can be called reflection or scattering.
The process in which energy is given off is called an exothermic change. The energy released can be in the form of heat, light, electricity, or sound
The light and heat given off by the sun is called solar energy. Solar energy is produced by nuclear fusion reactions in the sun's core, which create electromagnetic radiation that reaches the Earth.
Assuming you mean the type that was invented by Thomas Edison, it is the Incandescent Bulb. Light is given off by a coiled Tungsten filament that is heated by an electric current flowing through it. The amount of light given off is rated in Lumens, but most generally the consumer relates it to "Wattage". The higher the wattage the more light given off.
The material is called a photoemissive material.
It is a source of light that generates its own light, doesnt reflect off anything else
Bioluminescence is a source of light similar to phosphorescence. Both types of light emission involve the release of energy in the form of visible light, with phosphorescence having a longer decay time than bioluminescence.
A spectrometer analyzes the light given off when an element is burned.
