it is possible because the higher the frenqueny the higher the energy
The world survived many years without them, but they are very good at giving a fair amount of light for the energy consumed and they do last for a very long time.
Yes but not in the way you are thinking. The Moon reflects light but does not produce it's own energy.
Fireflies are remarkable in that they produce light without also producing heat. All of their energy resources are used very efficiently to make light energy without wasting heat energy.
Yes. It is a source of light and heat energy. Anything neither giving out light nor reflecting it will be impossible to see by our eyes.
no
no!
It is possible to convert other types of energy into light, and light into other types of energy; therefore it makes sense to consider that light, too, has an energy content.
light energy is important in your life because without light energy how will you see whats going on around you
Because the sun's light is white light as well.
Because efficiency is measured in Output/input. At the same light bulb output, one with lesser energy input required is higher in efficiency. Possible confusion come from description of low energy light bulb without stated the high or low energy is compared at what lux it can produce light.
light is a form of energy and energy cannot be destroyed or created only changed so the amount of possible light is equal to the amount of energy in the universe
spectroscope.....find out what kind of atoms are giving off light energy
