WebLight can also arrive at an object after being reflected, such as by a mirror. In all these cases, light is modeled as traveling in a straight line, called a ray . Light may change direction when it encounters the surface of a different material (such as a mirror) or when it passes from one material to another (such as when passing from air ... WebLight travels into the eye to the retina, located on the back of the eye. The retina is covered with millions of light receptive cells called rods and cones. When these cells detect light, they send signals to the brain. Most people have three kinds of cone cells, and every color stimulates more than one cone. on shore oil rigs https://summermthomes.com
