Bull's eye! (Posted on 2003-11-22) Difficulty: 3 of 5
Two points have polar coordinates as follows: θ=130,r=.35 (point A) and θ=70,r=.6 (point B). There is a surrounding circle, r=1, that acts as a mirror, and you wish to send a light ray from point A to point B by bouncing it once off the circle. What two alternative directions could you send it in (use an angular measure paralleling the θ coordinate it would have if directed from the origin)?

Hints/Tips The objective of the problem | Comment 11 of 16 |
Well, my original problem ment to calculate the angle formed between the reflected beams, but with flooble's re-wording is transcribed as "use an angular measure paralleling the Theta coordinate it would have if directed from the origin", that refeers to the aperture between the center of the surrounding circle, the point of reflection and point A. So, calculate 2*Theta or the angle between reflected beams.
