How are light rays coming from a point source of light different then larger source?
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.

What does it means when something has three shadows?
three different source of light from three different directions
Why are the colors of the spectrum different in each gas?
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.
How could you change the size of your shadow?
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.
When an object is moved closer to the light source will the shadow become bigger or smaller?
There are many things that could happen when an object is moved nearer to a light or further away. It could change temperatures.
Is a torchlight a natural source of light?
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.
What is the difference between light and reflected light?
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.
How do you make an object's shadow bigger?
To make an object's shadow bigger, increase the distance between the object and the light source. The further away the light source is from the object, the larger and more diffuse the shadow will appear. Alternatively, you can use a larger light source or diffuse the light to create a softer, larger shadow.
How can an electric bulb be considered as an extended source of light an as point source of light?
Either, depending on the situation. If you look at it from far away, the light seems to come from a single direction, and can be simplified as a point-source. If you are very close, the light comes from different directions, and such a simplification is no longer correct.
What is Light in Tagalog?
Liwanag or ilaw= light ( light coming from a light source) magaan = Light ( not heavy)
What will be the shape of wave front of light coming from a point source place at infinity?
The wave front of light coming from a point source at infinity will be planar, since the light rays will be essentially parallel as they reach the observer.
What distance is the light brightest dimmest?
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.
Why do shadows get bigger when close to a light source?
Shadows appear larger when close to a light source because the angle of the light rays hitting the object is more spread out, creating a larger shadow. As the distance between the object and light source decreases, the shadow becomes more elongated or enlarged due to the increased divergence of the light rays.
When you place something close to a light source will it make a big shadow or a small shadow?
The closer an object is to a source of light the larger the shadow it will cast.
Is your shadow bigger or smaller when you are nearer to the light source?
Your shadow is smaller when you are closer to the light source because the angle at which the light hits you creates a shorter shadow. As you move away from the light source, the angle of the light changes, resulting in a longer and larger shadow.
How is light from a hot source different to light from a cool 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.
Can a shadow appear larger depending on the size of the light source?
Yes, yes it can!
Why does light spread cause different temperature?
Light spreads out as it travels, which means the same amount of energy is distributed over a larger area, resulting in a decrease in temperature. This is known as the inverse square law, where the intensity of light decreases with the square of the distance from the source.
