Question:
Figure depicts a simplistic optical fiber: a plastic core (n1 = 1.58) is surrounded by a plastic sheath (n2 = 1.53). A light ray is incident on one end of the fiber at angle ?. The ray is to undergo total internal reflection at point A, where it encounters the core ?? sheath boundary. (Thus there is no loss of light through that boundary.) What is the maximum value of ? that allows total internal reflection at A?

The law of reflection states that the angle of reflection equals the angle of incidence ???????? = ???????? A bouncing ball obeys the “law of reflection,” which says that the ball leaves the surface at the same angle it approached the surface. The ball’s next bounce is 3.0 m to the right of its first bounce.
