That is any source of artificial light (not a naturally occurring light)
A light bulb is one example of a human-made source of light. The Sun is a source of natural light.
No, moon is not a light source, if we consider the moon as a light source, the mirror will also be called a source of light!!!! Every object seen by reflecting light from another object is called a non luminous body. As mirror, book, cup are not light sources, moon is not also a light source because it just reflect the light from the sun.
If you mean lighting inside a house then no. Natural light is the sun
If you mean lighting inside a house then no. Natural light is the sun
Lumosity refers to the level or quality of brightness emitted by something, such as a light source or a reflective surface. It is often used to describe the intensity or brilliance of light.
Your shadow will fall in the direction opposite the source of light - with you between the light source and the shadow. The direction of your shadow relative to you will depend on what direction you are facing.If you are facing toward the light source, the shadow will be behind you.If you are facing away from the light source, it will be in front of you.If you have the light source to your right, the shadow will be to your left.If you have the light source to your left, the shadow will be to your right.If the light source is directly above you, the shadow will be directly under you.If you move past a light source, your shadow will move from behind you to beside you and then to in front of you.
It depends on what you mean by "light". if you mean light that the human eye can visibly see without any other sources of light, then the answer to your question is none of the planets. If you mean light that the human eye cannot visibly see without any other sources of light, then the anwser to your question is all of the planets.
yes
Light is not naturally digital - perhaps you mean solid state? Digital light as in a fibre-optic cable is just laser light modulated.
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.
sodium light is not monochromatic but we consider it because sodium light is made up of two wavelengths i.e dichromatic having little difference in their values (5890 and 5896 A) n we take their mean value (5893 A)...........

Usually it means you are under "protection" Or Far more likely, there is a source of blue light nearby
