Spectrum gives UV rays or waves besides the usage of the sun
Black holes do give off gravitic waves, but according to non-string theory, no a convergence of electromagnetic waves in space do not create a black hole.
all moving objects
Melanin in cells give them their pigment and allow them to absorb different waves of light.
It's the focus
SONAR; SOund Detection And Ranging.
Warm objects emit infrared waves, which are a type of electromagnetic radiation. These waves are not visible to the human eye but can be felt as heat.
As far as we know.
Pulsar, since you would need some mechanical device to produce radio waves.
Waves get their energy from a source that causes disturbances or vibrations. This source could be wind, seismic activity, or the movement of objects in water. The energy is transferred through the medium in which the waves are traveling, leading to the propagation of waves.
Infrared radiation, which produces heat by transferring energy to objects through electromagnetic waves. This type of heating is effective for warming specific areas or objects rather than heating the surrounding air.
I had to think for this one but me being eleven I'm surprised nobody could answer but there are none on earth that i know of its in space a star, a star gives off radio waves.
A little more heat and a little less light than a regular incandescent light bulb.
Some objects in space that give off radiation include stars, pulsars, black holes, supernovae, and active galactic nuclei. These objects emit a wide range of radiation, from visible light to X-rays and gamma-rays.
Waves
by the particles in the sea when they bump togheter they give power to the waves by the particles in the sea when they bump togheter they give power to the waves

Objects that don't give out light are called "non-luminous objects." These objects reflect light that falls on them, making them visible to our eyes.
