From a point source, the light spreads out in all directions and adjacent light waves diverge from one another. From a larger source, it appears more like the light waves are moving parallel to each other, with little divergence. It's a relative thing. From the perspective of Earth, the Sun's rays are all parallel to each other because the Sun is huge and also because we are so far away from it. So the key differences are:
1. Small, point like source. 2. Being close to the source.
Combinations of 1 and 2 above produce more divergent rays.
Either of 1 and 2 below (or a combination of the two) will produce more parallel rays that don't diverge much.
1. Large light source 2. You're far away from the source.
three different source of light from three different directions
A spectrum is a function of the light source. A gas will absorb / emit light based on its molecular bonds, and different gases have different bonds.
You can either move closer to the light source or move the light source closer to you. The size of your shadow just depends upon how much of the light you are obscuring so the more you block out, the bigger your shadow.
There are many things that could happen when an object is moved nearer to a light or further away. It could change temperatures.
Torch light is NOT a natural source of light. It is an Artificial Source of light generated by the electrical energy. In this the electrical energy is being transformed into Light energy.
Source light is light coming directly from a light source/emitter (i.e. a light bulb, the sun, stars, etc.). Reflected light is light coming indirectly from the light source/emitter. That could be reflected, refracted light, etc.

Liwanag or ilaw= light ( light coming from a light source) magaan = Light ( not heavy)
The closer a light source is to your eye, the brighter it appears - intensity included. The closer you are to the source, the larger the angle of the cone; your pupil as the base and the source as the point. The larger the angle from the point, the more light entering your eye. Too close to the source and your retinal area becomes the limiting factor.
The closer an object is to a source of light the larger the shadow it will cast.
Yes, yes it can!
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.
As light gets farther from the source, the same amount of light spreads out over a larger area.
Depends where the light source is located and how many. Light will diffract around objects, so depending on the size of the object and the distance the light source is from it, more than one shadow can be cast, or at least it can have larger or smaller blurry edges which change when the light source is moved.
Day light, moon light, and any light coming from a general source that can be seen can be known ask Visible light
The photons spread over a larger area
Where light has bounced off a surface first, rather than coming direct from the source. For example, light coming from an object on a table such as an apple. There is no light in the apple, but light comes off it from a bulb or the sun.
