It explained that the smile was an effect that is known as gravitational lensing, which is a distribution of matter between a source and the observer during its travel towards the observer. WebThe geometry of a lens system is shown in Figure 12.2. A source located at point S is emitting light that is deflected by a lens located between the source and some observer, located at point O. The lens could be anything with mass: a star or planet, or a galaxy or cluster of galaxies. m7 laboratory\u0027s
