Question: In this problem we will consider applying Huygen's principle to the law of reflection. Consider three incident rays that hit a reflective surface making an angle O with the the negative x axis as shown. 3 e Figure 1. Three light rays 1, 2 and 3 are incident on a reflective surface at an angle 0. They hit the surface at point A, B and C respectively. Part 1) What angle does the wavefront for these rays make with the negative x axis? angle = Give your answer in radians. 0 is in radians. Part 2) The wavefront reaches C a time At after reaching A. Calculate the radius of the Huygens wavelet emanating from A at time At after wavefront arrived at A. radius of Huygens wavelet = m (put At as Delta*t in answer) Part 3) What angle does the reflected wavefront make with the reflective surface? angle = Give your answer in radians. 0 is in radians.
