If you're using it to generate light, 10 percent efficient.
If you're using it to generate heat, 90 percent efficient.
yes
Because semiconductors such as silicon are indirect bandgap semiconductors, so some of the light energy is wasted as lattice vibrations (phonons).
Yes. There is energy eberywhere. Jupiter gets light from the sun and produces light in its aurorae. There is thermal energy as it is not absolute zero, and there is kinetic energy from Jupiter's winds.
It is easier to see when it is yellow. It produces more heat energy and less light energy when it is blue. The yellow flame produces more light energy than heat energy. That makes it more visible
photosynthesise
Heat, which then produces light.
K+ produces the highest energy light. Na+ is a lie
Friction.
It produces Light Energy

bulb,flashlight,fluroscent light are some examples of light energy

produces energy for maintenance and repair of cells and tissues; produces energy for muscular activities and movement; prodices energy for nerve impulse conduction in animals and people; produces energy for light bioluminescent organisms.

It produces light and heat.
Efficiency=Useful energy output divided by the energy input. i.e. 100 J is the energy input and you get 5 J light energy from a lamp, the waste energy would be 5 J.
A light bulb uses electrical energy, and produces light, as well as heat.
The energy which produces light and heat in the Sun comes from "nuclear fusion" deep inside the Sun.
