The Answer is color. Because color has to do with light and physical properties.
When light strikes an object, the light can be reflected, transmitted, or absorbed.
A visible object that is not a light source is any other object in the universe. Objects that are not light sources reflect light and are thus made to be visible.Examples include:planetspeoplethe mooncarsdogsflowersbooksrocks, either in daylight, or else illuminated by a flashlighta light bulb or LED with the power switched off
Depending on the substance that comprises the object, light may be reflected, absorbed, or transmitted.
Visible light can be most effectively blocked using an opaque, dark-colored, solid object. A brick is only one example of an object that would qualify.
It means it radiates photons. This can theoretically be at any frequency. Heat, visible light, infra-red, X-rays etc. But it's normally a term used to describe visible light radiation.
Object that only shine with radio waves and not in the visible spectrum an object hidden by dust that block visible light.
The matter absorbs or reflects the light.
A visible object.
The light the object reflects.
angle at which visible light is reflected off the object.
The light the object reflects.
The moon is visible for the same reason every object is visible: it reflects light.

we see things when a light source goes into our eyes or when it reflects off an object
When the light falls on an object , then it can be visible to our eyes , because of light . This is called reflection on an object . Hence , the statement : We can see through a glass has a question that : How will we see through a glass ? So whenever the object is in the path of the light the object is visible to us .
