no because light from the light bulb is electrical and the sun is no. Light has the same speed from the Sun to Neptune as it is from the Sun to Earth, which is about 299,792,458 meters per second.

no because light from the light bulb is electrical and the sun is not. Does the sun give out natural highlights on light brown hair during the summer? know that the sun gives out light know that the sun gives out light know that the sun gives out light. How does the sun create sun and light? the sun creates light in a process called thermonuclear reactions. like, necular fusion.

Yet the British chemist Warren de La Rue had solved the scientific challenges nearly 40 years earlier. He used thin – and thus high-resistance – filaments to achieve the brightness, and delayed burnout by making them from high-melting-point metal sealed in a vacuum. His choice of pricey platinum for the filament and the difficulties of achieving a good vacuum made the result uneconomic, however.

Both the sun and the light bulb emit so-called "Blackbody radiation. This is the particular spectrum of light that's associated with the random thermal emissions of a hot object. Cool objects tend to emit more of their energy in the. Cool objects tend to emit more of their energy in the longer wavelengths like reds and IRs, while hotter objects emit more energy in the shorter wavelengths like blues and UV. (Note, there are other possible emission spectra, but those are associated with different materials doing the emissions and, for the purposes of this discussion, they aren't too important

Traditional light bulbs don't help plants very well because of two problems: spectrum and heat. Light bulbs produce a lot of heat and they don't provide enough power along the right wavelengths of light. Photosynthesis in different plants, at different stages, uses different wavelengths of light.

Traditional light bulbs don't help plants very well because of two problems: spectrum and heat. Anything not the right length can't be absorbed by the plant. Leaves are usually produced by blue shades of light, while the red and orange shades often spur fruit and flower production. Regular incandescent bulbs give off more yellow and orange light, starving leafy plants
