mirrors and lasers
this week in science class we learned about many things.......some of which insist of how water reflects your picture and if a laser pointer would be visible if reflected off of mirrors. we tested these experiments by using water, laser pointers,mirrors and reflective stuff. Dor the mirrors and lasers experiment me and my group gathered 3 mirrors and placed them in the appropriate position for our experiment. we then shone the pointer at a certain angle so that it would reflect off all the mirrors and onto the wall. Our results proved that the laser is infact visible when reflected of mirrors etc. and onto a wall. For our final experiment we simply poured water on different surfaces and tested to see if it was in fact reflective and that we could see our selves. On all different surfaces water will always be reflective to what ever is facing it.
