Please can somebody explain to me how and why light travels through glass into our eyes, as it doesn't in opaque objects?
Light can travel through glass because glass is a transparent material. This means that light is able to pass through without being absorbed or scattered. Unlike opaque materials, which absorb or reflect light, glass allows light to pass through it due to its molecular structure.
Glass is made up of molecules that have a regular, repeating structure. This structure allows light to pass through without being scattered. The molecules in glass are also very small, which means that light can easily pass through the spaces between them without being absorbed.
Opaque objects block light because their molecules are arranged in a way that does not allow light to pass through. When light hits an opaque object, it is either absorbed or reflected by the molecules, which prevents it from passing through the object.
No, not all types of glass are transparent. Some types of glass, such as frosted or tinted glass, have a different molecular structure that prevents light from passing through them. These types of glass are considered translucent, meaning they allow some light to pass through but not as much as transparent glass.
Yes, there are materials that can be added to glass to make it opaque. For example, adding metal oxides to glass can create a colored or mirrored effect, making the glass opaque. This process is often used in the production of stained glass or tinted car windows.
