Why does light get dimmer as you move farther away from the light source?

Background ResearchThere are several reasons why light dims with distance. One reason is the shape of the source. For example, if you are holding a flash light, the flashlight's source/bulb is a cone. Therefore, the larger the distance, the more dim it will be. The Light gets more spread out as the distance increases. If you had a piece of chewed gum, and you stretch it out, the thickness of the gum will be small. By doing this, this explains that light gets more spread out as the distance increases. The gum's size becomes bigger, as the gum's width becomes smaller. (WikiAsk)
Another reason why light dims with distance is because of the type of light bulb. Let's say you have an ordinary light bulb you bought from Home Depot. And then you buy a LED light bulb that is much more strong and gives much more brightness. Which do you think will be the brightest, regular light bulb, or LED light bulb. The LED light bulb.

∙ 13y agoThe light diffuses as the distance increases. So a flashlight, for example, would project a cone of light. As you move farther away, less of the cone's area would be striking you directly, so you see the source as dimming with distance.

How do you make a smaller and clearer shadow when you can not move the object?
Move the light source farther away from the object.
WHAT HAPPENS As a celestial object moves farther away from the viewer it will appear .?
brighter btw add me on fb @kevin garcia
What happens to the illuminance when you move away from the light source?
The intensity decreases.
When a source of light approaches an observer the light appears to be than it actually is?
Blue shifted and when it is moving away it is under a red shift.
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.
How does light rays move away from their source?
The light gets dimmer and eventually will die out.... it will only die out if the source stops giving off light. The answer man
What happens to the shadow as this light source moves?
As you move farther away your shadow get bigger and goes away
How absorption and scattering can affect beam of light?
How absorption and scattering can affect a beam of light is if the beam of light is farther away from an object, the light would be dimmer. But, if the beam of light was closer to the object, then the light would appear brighter.
How can absorption and scattering affect a beam of light?
How absorption and scattering can affect a beam of light is if the beam of light is farther away from an object, the light would be dimmer. But, if the beam of light was closer to the object, then the light would appear brighter.
Does the distance of the sun affect the power of solar energy?
yes, just like as a flashlight moves farther away, the light becomes dimmer and less bright
Why do you see more stars in the country?
You see more stars in the country because you are farther away from the bright city lights that drown out the dimmer light of the stars.
Which of these observations correctly describes the results?
The cells farther away from the light source are longer than the cells facing the light.
Describe how absorption and scattering can affect a beam of light?
How absorption and scattering can affect a beam of light is if the beam of light is farther away from an object, the light would be dimmer. But, if the beam of light was closer to the object, then the light would appear brighter.
How do you make a smaller and clearer shadow when you can not move the object?
Move the light source farther away from the object.
What a celestial object moves farther away from the viewer it will appear .?
It will look dimmer and dimmer. Also, smaller and smaller (the angular diameter gets to be smaller and smaller).
What As a celestial object moves farther away from the viewer it will appear .?
It will look dimmer and dimmer. Also, smaller and smaller (the angular diameter gets to be smaller and smaller).
A bright star can appear dimmer than a less bright star if the bright star is?
Farther away!
