Uses Of Light

I'm doing a project in school and i could use some help. Can you help try and find ways to prove about the laws of reflection, and different uses of light in everyday and special uses.

I'd really appricate the help =D

Oh, and i'm sorry if this is in the wrong place. If it is feel free to move it =)

 

Here's one way you can prove the laws of reflection.

Draw a vertical line on a piece of paper. This line is called the normal. Place a mirror facing you perpendicularly to the normal. Shine a ray of light, this is called the Incident Beam, at the mirror at any angle, from the mirror to the beam is called the Angle of Incidence.. The light will bounce of the mirror at the same angle as the Angle of Incidence, this is call the Angel of Reflection.

here's a diagram.

 

You could also explain how light works in a laser.

 

We just had to do something like that, I brought in glass bottles of different colours and shined them with a flashlight when the class lights were off and the shades were drawn, it normally projects the lights of the bottles like a rainbow. The light defracts off the glass and projects it in the direction you shine the light.​
