what are transparent and opaque substances?



When beam of light hits an object, three things can happen. It will either pass through it, be reflected off it, or be absorbed by it. Transparent materials are those that allow light to pass through them. We can see clearly through transparent materials like water and glass. Sometimes, however, the surface of even a transparent material such as glass can be reflective, and light will bounce off it. Some materials known as translucent materials known as translucent materials allow light to come through, but we cannot see through them.

objects through which light cannot pass are called opaque objects. When a ray of light hits an opaque object, it will be reflected in all directions, and the light is said to be scattered. The reflected light reaches our eyes, and allows us to see the object. A shadow will be cast behind the opaque object, where the light cannot reach.
