drawing in question 7ci 37:20 is wrong, angle of i is equal to angle of r, we can draw a tangent on the bottom wire according to the curve and measure the angle of incidence, in the marking scheme it mentions that there will only be one reflection on the bottom wire and end on the left of the diagram, please correct.
