Plasma
The phases of matter that can give off light are primarily gases and plasmas. In gases, when atoms or molecules are energized (for example, by heat or electricity), they can emit light as they return to lower energy states. Plasma, a highly ionized gas, emits light due to the presence of free electrons and ions that can emit photons when they recombine or transition between energy levels. Additionally, certain solid materials can also emit light when heated or excited, such as in the case of incandescence.
Dark Matter throughout the Universe does not give off or absorb light.
They do, as they are respiring 24 hours each day. Plant respiration occurs in both the Dark and the Light phases: only the [photosynthetic] Light phases produces a NET GAIN of O2.
We see the suns' light reflecting off the moon. There is some of the Earths' light also. The sun illuminates the moon as it orbits the Earth a give it the phases we see.
yes it does give off light
The phrase 'give off light' means to have a lot of light.
Matter that does not give off electromagnetic radiation is known as dark matter. Dark matter does not emit, absorb, or reflect light, making it invisible and detectable only through its gravitational effects on visible matter in the universe. Its exact nature and composition remain unknown to scientists.
The moon reflects light from the sun, which is why it appears to give off a bright white light. The moon's surface reflects different amounts of sunlight depending on its position in orbit, resulting in the various phases we see from Earth.
Planets and Moons only reflect light, they do not 'give off light'.
A rose does not give off light
The stars give off light
Plants give off oxygen gas in the light.
