The matter absorbs or reflects the light.
when a light is shining a peice of matter can et in the way of the light
Dark matter is invisible. It doesn't interact with light.
The Answer is color. Because color has to do with light and physical properties.
No. Light is energy, not matter. Therefore it is not a substance.
Glass?
yeah its light . if light has matter it obvious has weight, if it passes through us we would even fall some times
Anything that can reflect light is only visible to an eye... others which cannot are dark..
Through four processes. Emission, transmission, absorption, and reflection.
No, you cannot see a beam of light in space. In order for light to be visible, it needs to interact with matter and be scattered or absorbed. In the vacuum of space, there is no matter to scatter or absorb the light, so the beam itself would not be visible.
Fluorescence
Yes! Light travels through any material that does not completely absorb it. Visible light can only travel through materials that are called either transparent or translucent. Visible light travels through glass all the time. Visible light also travels through your cornea and the gel-like material that is in your eyeball. There are other types of light than visible light, such as ultraviolet (UV). UV is light that has more energy than visible light. This is the type of light that can give you a sunburn. There are even more energetic types of light like X-rays. They go through lots of material that visible light can't -- like skin and organs, but they do not go through bones or teeth very well.
transparent, translucent, and opaque. All 'materials' (i.e. made of matter) interact with em wave energy (which includes light). Humans can detect some but not all of those interactions.
