- Q: And How long is a light year?
- According to the web site, The Unmuseum - Speed of Light, light travels at 186,000 miles per second, or 700 million miles an hour. This is a very informative and interesting article. Another web site you might try is The Speed of Light according to the Univ. of Va Physics Dept. As Captain Kirk, the commander of the Enterprise used to say, beam me up Scottie! A light year is the distance light can travel in one year.
- Q: Any kind of light, such as -but of course not limited to- starlight, sunlight, city lights, even light within. Let me know the name and artist its by thanks =]
- Green Light - John Legend
- Q: If anything travels at the speed of light, it would travel infinitely into the future instantaneously according to Einstein's theory of special relativity, as one cannot exceed this velocity.Well light travels at light speed, or at least our senses and measuring tools designed based on our logical input reveal that light travels at light speed.So does this mean all visible light is the same age it was when it was first created in the universe? Because time slows to nill for objects that are at the speed of light and light is?
- Title question... We cannot know what time sense light has. We cannot apply the Lorentz transforms to anything moving at c, and there are no reference frames moving at c. First statement... Nothing can travel at the speed of light, that has mass, and experiences time. Second question... We cannot tell how old light is. If we were God-like and traveled with light, it would be a stationary EM field. It does respond to polarizers, gravitational wells and such, not infinitely but proportionately. So it does not make sense to assume they are timeless. Third question... Light is not an object, it has no mass, no reference frame. Virtual photons travel all possible speeds and follow all possible paths, with no c limitation (except on average). This is an old question, and the laws of physics for massive objects *does not apply* to light. So you will find no satisfactory answer to your question.
- Q: I have an overhead light and some plants in my room. If I was to put in a grow light instead of the normal light bulbs I use, would it light my room to the same degree? Are there any problems with doing this?
- What type of grow light is it? Grow lights can vary: One type is high intensity fluorescent (which is great for lighting rooms and plants) or either a metal-halide or high pressure sodium light (which you wouldn't want to use to light a room, it would be an ugly orange glow)
- Q: why does flourescent light use less energy?
- Fist off neon lights work by passing an electrical current through the gas Neon (Ne on periodic table of elements) that is sealed in a gas tight container. Now when the electrical current is passed through the light the electrons jump from different energy levels, which emits energy in the form of light in different colors. You see each element, for instance Hydrogen, Neon, Lithium, etc. emits its own special color when energy weather it be from electricity or even heat. Your second question...: A Fluorescent light uses less energy because they are filled with mercury which is a liquid metal that takes less energy to conduct electricity because it is both a metal and a liquid. By doing this the light bulb emits less heat to. Hope this helps--
- Q: can the incandescent light can be substitute to sunlight in growing the plants healthy?
- Sure. The differences in the light have to do with the amount of energy distributed across the spectrum. Incandescent lights have more infrared (heat) light than higher frequencies (red, orange, yellow, ...). So getting too much heat can sometimes be a problem, but so long as you have enough light, indoor bulbs can work fine.
- Q: I know there are, but are there any light sensitive materials that react differently when exposed to light in its three forms (red, blue, green)? I am basically asking if there is a material that reacts to light, and if so, differently to red, green, and blue light, and produces different chemical or electrical output for each of the three.
- There are many materials that react to light, not only red. blue or green but many other types of light like ultraviolet light or infrared light. have in account that red, green and blue light have different energies (blue more than green more than red) which means irradiating a substance with any of these types of light may produce different chemical reactions or physical changes. A good example of a substance that reacts with light is vitamin D s produced by your skin in response to exposure to ultraviolet radiation from natural sunlight, another example of a substance is chlorophyl which absorbs energy from the sun light starting a chain of reactions called photosynthesis.
- Q: Scientifically is there any difference between artificial light and natural light?
- Light is light, whether it's from the sun or man-made. Although natural light is from the sun, so it will compose the whole spectrum - including visible and invisible (microwave, infrared) light.
- Q: I have a 2000 Honda CR-VThe back, driver's tail light doesn't turn on. I replaced the bulb, which was when I noticed that the break light and the tail light are both the same light--however, the break light DOES work, but the tail light doesn't. This doesn't really make sense to me.Every other tail light works, except for that one. What could this mean? Is there something I'm missing?
- Check for burnt socket and the two hot sides for voltage. Also check ground continuity on that side.
- Q: what the characteristics of light received from stars? :/
- Roughly the same characteristics as light received from our sun, or even a light bulb. Light is the transmission of energy from a quantum energy packet called a photon. I would say that the light received from a star is really old, but a photon is not actually effected by time. The photon travels at the speed of light, and so would not experience time or be effected by it. The light we receive from stars is very coherent because of the long distance involved, the photons are exceedingly parallel.
