- Q: did any one think that the light is the original energy?And can you explane if there is or not 'a different between light and heat?can I have light without heat?can it be heat without light?
- Light is one form of transformation of energy. The one that emits light is called luminous object. Energy from the object is transmitted into the space in the form of light energy. Similar to light rays we have many other rays such as Gamma rays, X-rays, Microwaves, ultra violet rays infra red rays and radio waves [short, medium and long] waves. All these rays belong to a family called electro-magnetic radiation and energy from an object is transmitted into space All these rays transmit energy at a speed = 3x10^8 m/s, a value which cannot be exceeded by any material objects. The main characteristics of all these radiations are the frequencies of the wave. Their frequency difference gives them different characteristics and properties. Though heat energy is transmitted by conduction and convection, there is another method of transmission of energy called radiant heat. This radiation of heat energy is again electro magnetic radiation. Below 600? C all objects emit heat energy. These radiations are not sensed by our eye, but our skin feels this energy. When we are near a stove we feel hot due to this radiation of energy. When the temperature raises more, high frequency waves are emitted. These frequencies are sensed by our eye and we call these light rays. When the temperature is nearly 1000C we perceive white light (a mixture of all ways sensed by our eye) When the temperature is more than 1000C ultra violet rays are produced which cannot be sensed by our eye. The other rays gamma and X rays cannot be produced only by heating. Thus heat rays and light rays are all belong to one family called electromagnetic radiations.
- Q: what is light? plz explain it?
- Light is loose momentum, looking for a charge to prang. We model it as a wave, and it looks and acts like a wave. We model it as a particle, and it looks and acts like a particle. Beyond this, all we have are words that describe what it is like, that color our mind to look at this other distortion of Nature. Light is.
- Q: The frequency of yellow light is 5.1 1014 Hz. Find the wavelength of yellow light. The speed of light is 300 000 km/s___m
- frequency = speed of light divided by wavelength so to find the wavelength, use this formula wavelength = speed of light divided by frequency so ... 3.00 x 10 ^8 m/s (this is the speed of light in scientific notation) ------------------------ 5.1 x 10^14 1/s the wavelength is 5.9 x 10^-7 m
- Q: why does gellyfish fluoresce uv light?
- They fluoresce because they produce proteins which reflect UV light. So when we see the UV light we are seeing the reflection off of these proteins. One such protein, used to stain many things in cells in GFP (Green fluorescent protein), which comes from the jellyfish Aequorea victoria/Aequorea aequorea/Aequorea forskalea.
- Q: For a long time I've wanted a blacklight but I never got one, so can you please tell me how to make one of those black light bulbs! Do you put some tipe of black stuff on a light bulb or something???
- you cannot make a black light. ps the regular incandescent ones dont work very well. spend a little extra money and get a fluorescent.
- Q: What is light? most light is from a light bulb but what makes it well...LIGHT!? what light sorces are there and what and why it makes them light up?
- What your calling light is electromagneitc radiation in a frequency that your eyes can see... Anything releasing those frequencies of electromagneitc radiation could be considered a light soruce (flames, lasers, etc...)
- Q: How does the amount of light (at different distances-close, far, no light) affect the rate of photosynthesis?
- Generally, the higher the light intensity, the faster the rate of photosynthesis. However there will come a point when further increases in the light intensity will have no effect on the rate of photosynthesis, because the rate is now limited by another factor, for example carbon dioxide concentration.
- Q: How does light do this?For example, when astronomers at NASA sent Curiosity to Mars, I recall them saying that the photons of light affect particles soaring through space by hitting them and moving them.I also remember that the photons of light moved the Curiosity rover about 300 meters off course, but astronomers also calculated this and re-adjusted the Curiosity rover to soar about 300 meters to the left to prevent going off course.According to Isaac Newton Force = Mass x VelocityForce = 0 * cForce = 0?How does something with 0 force alter the course of a projectile?
- Light has no rest mass, at the speed of light, it is not at rest.
- Q: Why do light colors reflect more light than darker colors?I already know that white absorbs less colors therefore reflects more and black, its the oppositeBut my teacher is asking WHY its like that? Why does it work that way? Anybody know?
- The darker a color is, the more black is mixed into the color. When you look a red apple, you see red because when light hits the apple, all the colors except for red get absorbed and only the red color is bounced back from the apple into your eyes. So you only see red coming from the apple. Black in essence is a color that does not reflect any light. So when you see something black you are not seeing any colored light bounce back from it; on the other hand white objects reflect all the colors back because white is a combination of all the colors of light. Dark colors then, since they have more black in them than white, will absorb more colors, and lighter colors, since they have white, will reflect more.
- Q: which lights driver should use inside tunnel ?
- Regular beams.
