Re: Optics B/C

Hello, Thanks a lot for all your help. I finally understood it after your help. If I saw that problem on the test I would just take my graphing calculator and plug in y=1.66sin(x/2) and y=sin(x) and see where they intersect. This method gives the answer of ~67.78 degrees. I went ahead and plugged th...

Re: Optics B/C

Hello, This question popped up in one of the tests I took recently. "Light is incident on a piece of flint glass (n = 1.66) from the air in such a away that the angle of refraction is exactly half the angle of incidence. What are the values of the angles of incidence and refraction?" I went ahead an...

Re: Optics B/C

Hello, My team recently went to an invitational and found out that the TP (target point) was off 5 cm from the center line from that particular invitational. The team reviewed the rules once again and it says that event supervisors select a TP that is the same for all teams. Does this mean that even...
