Opaque materials are substances that do not allow light to pass through them. When light strikes an opaque material, it either gets absorbed or reflected, but you cannot see through it. For example, wood, stone, and metal are opaque materials. ...

Transparent materials are substances that allow light to pass through them easily, so you can see objects clearly through them. For example, glass and water are transparent materials. When you look through a transparent material, the image on the other ...
