No. Consider florescent lights and florescent sea life.
Stars.
Light bulbs convert energy to light. This conversion is inefficient, meaning that not all of the energy will convert to light because of the design of the bulb and the laws of physics. The energy that does not become light is released as heat, and that's why a light bulb gets hot.
No, everything that we can see (besides objects the produce light eg sun, light bulb) reflect light. If it didn't reflect light we would not be able to see it.
Anything hot enough - topped by stars.
It depends the type of plate.
Illuminated objects
the sun
Stars.
Sun and other stars, like Sirius are able to produce light of their own.
When some objects get hot enough, they glow, given off a faint red light . If they get even hotter, the glow turns into white light. The objects are said to be white light
Non-luminous. Objects which produce light of their own or give out or emit their own light are called luminous objects. Objects which do not produce light of their own, on the other hand, are called non-luminous objects. Luminous objects are objects like stars, sun and other celestial bodies which give out their own light. Objects surrounding us are not such light emitting objects. Therefore, we are surrounded by non-luminous objects.

Fluorescent or incandescent.

it does because the heat on the light causes the object under it warm
Anything hot enough - topped by stars.
Light bulb, Lamp, Sun, Screens of electronics, cameras, and Lightning.
