Title: An Unknown Light Can be Freighting


1
An Unknown Light Can Be Freighting
2
A couple of years ago I went camping in a
secluded plot of land a friend owned.
3
There was no one out there that night except for
me and a group of friends.
4
We were all gathered around the campfire one
night and noticed a beam of light coming from
behind the trees about 100 feet away.
5
The light was moving around aiming at us then
swinging up into the sky like a spot like.
6
None of us knew what the light was or what it
was coming from.
7
Of course, all the girls start to get scared and
run into their tents.
8
While the three guys myself included muster up
the courage to go see what the mysterious light
is.
9
The three of us start moving towards the light
within the trees.
10
As we get closer my friend Brad starts to get
scared and decides to turn back.
11
Encountering The Mysterious Light
12
Now at this point it is just my friend Ian and I.
13
We make it to the other side of the trees and
see a clearing with a bright light emitting from
the center.
14
I tell Ian that I am going to get closer and see
what it is, but Ian seemed to be so nervous and
tells me I will just stay here.
15
I decide I am going to see what this light is no
matter what.
16
There I go by myself into the clearing walking
straight to the light.
17
The light seemed to get brighter as I got
closer, but once I was about 20 feet away I
noticed it was a truck that just had a lot of
lights on it.
18
I am now wondering who this could be we should
be the only ones out here, as I walk up to the
side of the truck.
19
There is a person setting up a deer blind.
20
He notices me and jumps up from what he was
doing.
21
My adrenaline is kicking in and I am ready for
whatever is about to happen, but as he turns and
we make eye contact I notice that it is my
friends dad that owns the land.
22
A sigh of relief was let out from the both of us.
23
After explaining to him what happened, he
apologized and said he didnt realize that we
were in that direction.
24
This encounter has always made me curious how far
a flashlight or lights can be seen.
25
So I did a little research about how light
travels.
26
How Light Travels
27
The way light works is it is projected from its
starting point.
28
Lets say you are using a flashlight.
29
The light the flashlight emits is actually
photons in a cone shape.
30
The further the photons get from the source the
thinner and more spread out they become.
31
Eventually coming to a point where the naked eye
is unable to see.
32
Photons are continuous meaning that they will
never stop, but after becoming so thin they
basically turn invisible.
33
Can Light Be Seen At Extreme Distances
34
Like I stated earlier about how light is photons
and the photons thin out after so far.
35
You can actually control how far you can see the
light from your flashlight to a certain extent by
focusing the beam.
36
The more focused you have your light the further
it will go.
37
On the downside the more focused the beam is,
the less the light will cover width wise.
