objectives: HP Stuff Parallax Reflection

we started off class with a general reminder that all Hershey Park permission slips are due this friday. after that we took a look at a few demos which pertained to the reflection. next we received a red plastic thinger in which we looked through it at two masses, one being in front of the other, and we are suppose to line them up so that the refection of the one in front would match up with the mass in the back. the we were suppose to measure the distance between the red plastic thinger and each mass. Then we did it a second time changing the location of both masses, fun right? our group found that both distances were the same. so it seem to be that if n object is a certain distance away from the mirror then the other object behind the mirror would have o be the same distance away as the first object.



after that we did another demo with that had to do with reflection. we took the mirror and a piece of string and had two people holding the string. the two people were able to see one another through the mirror. then we had two innocent by standards look along the string and they were able to see each other plus the two holding the string. what we learned from this is that the angle that would be reflected off the mirror would be th same as th angle of the ray going into the mirror.
