There are several places where someone can learn more about the speed of light. One can go to the local library and read some books on this subject. They can also find more information online on sites like Curiosity Discovery, Wikipedia and the Department of Mathematics.
A person can learn more about recumbent cycling from several different places. Some of these places include Light Foot Cycles, Cycle Genius, and Recumbent Cyclist News.
According to our understanding of physics (which is always subject to revision and reinterpretation as we learn more) it is impossible to travel AT the speed of light. A spacecraft with sufficient power can go very CLOSE to the speed of light (although because of the interstellar gas and dust, it would probably be quite dangerous to do so!) but can never actually REACH the speed of light.
To convert frequency to wavelength, you can use the formula: wavelength = speed of light / frequency. The speed of light in a vacuum is approximately 3.00 x 10^8 meters per second. Dividing this speed by the frequency in hertz will give you the corresponding wavelength in meters.
A tachyon
No. Light slows down whenever it passes through water. Nothing is faster than the speed of light in a vaccum.
The speed of light is more than 850 thousand times the speed of sound.
No, according to the theory of relativity, it is impossible for any particle with mass to reach or exceed the speed of light. Accelerators can increase the speed of particles to high fractions of the speed of light, but they cannot exceed it.
Do you mean a light SPEED ship? Ignoring the possiblity of "warp" technology, which, though potentially faster than light, does not really address the problem of achieving light speed, but circumvents it: As speed increases, so does mass. The increase in mass is imperceptible at the speeds you and I commonly travel, and even at the enormous speeds (but still nowhere near light-speed) achieved by the space shuttle. However, at speeds near light speed, mass increases assymptotically. At light speed, mass is, in fact, infinite. If a ship was attempting to attain light speed, its mass would increase more and more with each additional unit of speed. As it gets closer to light speed, the mass would be so great that no amount of thrust would be able to get it TO light-speed. The mathematical proof of this is somewhat more complicated, but take my word for it - it's impossible.
No, a person can not run at the speed of light. To make something move faster and faster you need more and more energy, and the more mass it has, even more energy it needs to move. The reason why light can travel at its own speed is because it has no mass, and it would take an infinite amount of energy to make something with even the slightest amount of mass to make something move at the speed of light.
You can learn something about almost any object based on how it reacts to ultra-violet light. You can learn about how some cells are effected more then other cells by exposing them to UV light, you can also learn a little bit about the atmosphere of a planet by shining light on it (including UV light) and see what light is bounced off and what light it not.
Theoretically there exist hypothetical particles called tachyons which can travel faster than the speed of light.
No, the speed of light in a vacuum is constant and is approximately 299,792 kilometers per second. This means that light always travels at this speed regardless of the observer's motion or the source of the light.
