Lasers, what a cool thing (no its not). Shut up Subconscious, no one likes you. Anyway, back to my point, we recently did a project involving the Pythagorean Theorem and Law of Reflection.

The Pythagorean Theorem states: a theorem attributed to Pythagoras that the square of the hypotenuse of a right triangle (a triangle with one of the angels being 90 degrees) is equal to the sum of the squares of the other two sides or A2 + B2 = C2.

The Law of Reflection states: a statement in optics: when light falls upon a plane surface it is so reflected that the angle of reflection is equal to the angle of incidence and that the incident ray, reflected ray, and normal ray all lie in the plane of incidence.

In this project we had to point a lasers at server all mirrors to prove both of these statements true. How? The length between the distance of the mirrors would prove A2 + B2 = C2 and the angel that the light is reflected off the mirror will prove the law of reflection. Here are some pictures of our display (the pictures are really bad)

To see the laser, a teacher sprayed smoke over it, but our laser wasn’t powerful enough to see. That was sad. But anyway, we still had a cool box around it. Some of the criteria for this project were:Questioning and predicting: Demonstrate a sustained intellectual curiosity about a scientific topic or problem of personal interest,Communicating and Representing: Represent mathematical ideas in concrete, pictorial, and symbolic forms and  Applying and innovating: Co-operatively design projects. The first of these ment completing the worksheets we were given in class, the second one was for creating a model of the laser display online, which I have a picture of. And finally, the last criteria is how well I worked as a team (oh way. I forgot to say I was in a team. My group members were: Jupiter, Kira, Mackenzie and Frankie. Check out they’re blogs).

See you next time.
