I am confused on how light rays behaved in this figure, specifically when it passed through the diverging lens. Why would the light rays converge when it passed through the diverging lens, when it should have diverged? Shouldn't the light rays have diverged instead? This was from a textbook and how zoom lenses work.
This was how I pictured the light rays would be. The blue lines would be the normal lines. Is it not correct? I mean light rays should have bent away from the normal lines since the light ray was entering through a material with lower index of refraction.
