Leave a reply below as an answer to the following question. You will need to finish graphing all three of the light bulb's lux readings in order to answer this question. After completing the graph what can you infer about the relationship between luminosity and distance from source? Do your best to give a thorough and complete response.

It does matter because the light gets lower and lower because the lux gets lower because of the distance so the light goes in all directions meaner there is less light so lasers focus the beam so it can go farther.

The relationship between luminosity and distance from source is interesting. A simple answer is that when the distance gets farther away the luminosity gets smaller. As shown on our data a bright light from a really close distance has a very bright luminosity. However, if you were to move, 10 feet back then it would show a different luminosity. They go together on a graph. When you move back the luminosity goes down. It is like the metaphor Jeff gave us. the more sleep, the better grades. The less sleep down go the grades. They move together like a package. Together.

Adding on to the first section I wrote, the LUX goes down from a farther distance the light has more room to spread out and disperse. When you are closer to the light it's more concentrated, therefore causing a higher LUX.

The farther away you are from a light bulb the lower the lux will be.

If you are to move the light farther away, it gets smaller and the smaller the lux will be, if you move it closer to you, the lux goes up and it gets brighter.

As you move farther away from the light, the luminosity(lux) gets lower.

The luminosity will grow less as you move away form the light but, once you hit zero the luminosity will stay at zero because to go into a negative number here one would have to go to the opposite of light, which is dark, but if it is dark what is the luminosity?

When the luminosity is moved closer to you, it appears brighter, but it is actually the same brightness, it just changes in your eyes when the measurement changes.

When the *light* is moved closer…

As you move away from the light, the lux drops. And as you get closer, the lux grows. When moving away the light seems dimmer, but our eyes can't see that it's the same.

I think the closer the light bulb the brighter it will be. The farther away the least bright.

The relationship between lux and distance is the farther the distance the less lux radiates from the light bulb.

The light bulb will look brighter if it is farther away or if it has more wats.

The lux goes down as you get farther from the source.

The farther away from the bulb you are, the more the lux decreases. The closer to the bulb, the higher the lux.

The greater the distance the lower luminosity.

The lux decreases as you retreat from the object

As you get farther away from the lightbulb, the lux (or luminosity) decreases. First only a bit, then a severe drop and then more small decreases as there isn't really much to decrease from. An example fall is this: 850, 541, 230, 180, 90, 50, 20, 10, etc. No, there is no relationship that these are approximate halves of each other, I'm just guessing. However, when you move closer, it gets brighter, no duh, so the lux goes up.

Also, the relationship between the two is that it drops fast then slows in its dropping.

As the object gets further from the source of light less light hits that object. Luminosity decreases when it gets further from the source.

The relationship between luminosity and the distance from the source is that the further away you are from the source of light the less luminosity.

It does matter cause the farther away you are from the source of light the luminosity goes down cause the lux go down and then you just flip it for closer.
