1. White light passes through two perfect cyan filters in a row before striking a wall painted magenta. What color does the light appear to be where it strikes the wall? 2. A 50% solution of glucose in water has a critical angle for total internal reflection of 45 degrees. Suppose a beam of light passes from the air down into such a solution at an incident angle of 45 degrees. What angle will the beam make in the solution?

Answer 1

2 when Passing through Cyan filters, it will absorb only cyan ne green blue] Combination from white light. So, when it shikes the magenta Colour Wall, it will appear as Blacko - Oc= /450 y At incident angle Q=45, ie. critical angle, the beam will graze from the interface of air ano Solution mediem. So the angle that the beam makes in the solution will be 90° solution
