Photographic film changes its chemical characteristics according to how much light strikes it. Light can also cause electrical changes to occur in some materials. For example, a solar cell creates electricity from light. The retina in your eyes goes through chemical changes that creates electrical impulses when light strikes it. An example of this is when sunshine warms your skin.
Light can cause electricity to be generated, like with a solar-powered calculator.
Light can cause chemical changes, as seen when plants use light to grow. This is also what happens when colors fade from sunlight or when photo-sensitive sunglasses get darker in bright light. When light strikes an object, some of it can be absorbed. That is how an object gets warm when exposed to sunlight. Light is also reflected off of objects.
