Title
The brightens of splitting light between two mirrors.

Problem Scenario
When you take a 90* angel mirror, and take a projector, computer you can tell how much light is reflecting off of the 180*mirror.

Broad Question
What happens to the brightness of the light when the light splits?

Specific Question
What happens to the brightness of the light when the light is split?

Hypothesis
The levels of light would be to bright for the light sensor to handle.

General Plan
1. At the beginning of my experiment I started out by setting it up.The first thing I did was I got a cardboard box and put a medium sized mirror on each side of the box. I took a projector and a laptop into a dark room and I recorded the brightness of the reflection coming out of the projector reflecting off of the mirrors.I used a light sensor and a lab quest to collect my data.

Potential Problems And Solutions
While performing my project I found that I had to be extra careful with the pieces of glass so I didn't get cut with it.While I was operating the projector I found that I needed to be careful of where I put my hands on the projector do to the heat it gave off. The heat was hot enough to burn you.The light was bright enough to hurt your eyes if you looked at it to long.

Safety Or Environmental Concerns
The only thing to be careful about is the sharp corners of the mirror,the heat and light off of the projector.

Detailed Procedure
When you take a 90* angel mirror, and take a projector, computer you can tell how much light is reflecting off of the 180*mirror, and take a lab Qwest and a light senser.

Discussion
My experiment on measuring light could be improved by using a different distance,a brighter light and using a longer ruler. By using a longer distance this could help the brightness of the light when it is reflecting.By having a brighter light it would give you more reflection off the mirror. If i have a longer ruler it would easier to measure.By doing this project I feel it has helped me to learn about light and distance. I would recommend to make a car that has one light this would save money and energy..

I chose to do my experiment on Light. The purpose was to measure the brightness of the light coming off the mirror.This experiment was to try to have a one way light bulb for cars. I found that by doing my experiment it could change they way cars use lights.
