A parallel beam of light falls on a wedge with an opening angle a=1° and a refractive index n=1.5, normal to its face AB. Behind the wedge there is a collecting lens with a focal length F=180 cm. Face AB is perpendicular to the main optical axis of the lens. There is a screen in the focal plane of the lens. How much will the light point on the screen move if the wedge is removed?
