Artificial light will not kill plants. Natural sunlight is best for plants and should be given to plants even when artificial light is used.
Yes, the sun does produce (UV) ultra violet rays.
Light in the region of 10nm - 400nm in wavelength
Yes.
no
The warmth you feel come from the Infrared rays.
Black Holes don't give off radio waves. They emit X-rays. This happens rarely since the black hole's gravity is so strong that it doesn't allow photons to escape.
as far as i know... the earth doesnt give off rays.
Spectrum gives UV rays or waves besides the usage of the sun
Yes.
This is true of LED lights
Scientists can detect black holes by using x-rays and gamma rays. Black holes still can release matter, and black holes give off a lot off x and gamma rays.
Sunspots do give off magnetic rays.
No a plant will die and shrink because of the UV rays that the black light give off.

galaxies give off and ray called ray romano

Because they give off absolutely no light and no radiation. The only radiation is X-Rays from the stars being sucked in.
All people what or black give off heat.
switch lights off
