A small light source is called a flashlight or a torch.
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.
It is called a closed circuit. This means that the electricity can flow continuously from the power source to the light bulb and back again.
A straight beam of light is called a ray of light. Rays of light travel in a straight line from their source until they are interrupted or reflected by a surface.
The source of light energy is typically the sun, which emits light through a process called nuclear fusion in its core. Other sources of light energy include artificial sources such as light bulbs and fire.
In a fluorescent light source, electrical energy is converted into light energy through a process called fluorescence. This involves passing an electrical current through a tube filled with a gas and a small amount of mercury vapor. The electrical current excites the mercury atoms, which in turn emit ultraviolet light. This ultraviolet light then causes a phosphor coating on the inside of the tube to fluoresce, producing visible light.
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.
Our sun is the source.
When hear energy is converted to loght energy it is called hot source of light (sun light). when light source is produced from (generally reflected light, moon light) a cooler object.
Light from a small light bulb behaves in the same way light from a bigger light bulb. When you say wide, I assume you mean to ask about light from torches. Light travels in straight lines. If light hits a surface, it will be absorbed or reflected, there are no exceptions. So if light is emitted from a 'wide' source, it will be able to travel to a larger area, lighting up more, but at a lower concentration. If the same amount of light is emitted from a large or small source in the form of a beam, the same applies. The smaller the beam, the more concentrated the light.
if you mean the small shadow, its the penumbra
A small, portable light source.
Light source, can be mirror or electric light.
The mirror, which can also be called the light source. It reflects the light.
The closer an object is to a source of light the larger the shadow it will cast.
This phenomena is called metamerism. It occurs when two colors appear to match under one light source but not under a different light source.
You can not collect light.
