Light Travel

Light is one of the most mysterious of the universe. Imagine a world without light, and will realize the important role it plays. It is the first to think carefully about this question - "How to get the light?". Galileo's two Einstein, Maxwell, each one of the great minds have thought about this issue, and because he knows the

answer to that question. But much remains unknown about light.How fast light travels? This is another question that needs an answer.
The researchers measured the speed of light to travel 299792458 meters per second! This is the highest rate that can be achieved. Far been without any difficulty to cruising speed in excess of the speed of light! The speed of light is constant in a vacuum. In fact, one of the main pillars of modern physics, which is a special theory of relativity, the speed of falling light is known to be overtaken by another object. In short, the light is the fastest, as in our universe, and no information can travel faster than light. How easy it is to achieve this phenomenal rate? Because light travels at all? See the answer to that question.

As the light travel in space? In response to the question is - "How to travel light?" You should first ask: "What light is made of?". The answer to this question, the first is the answer to that.Can understand how to travel light when I realized what constitutes the natural light light.The was fully explain the ingenuity James Clark Maxwell. It came as a great revelation to him when he was a design theory, which describes the electric and magnetic forces of power between stationary objects and moving loads! He discovered that electricity and magnetism are two sides of same coin? His theory of co-generation of electricity and magnetism into a single force of electromagnetism and light it was found that the electromagnetic waves!

Light travels as electromagnetic waves from space is a kind of light waves! But each square, somewhat vague. A growing wave as a wave of the sea is the environment in which it operates and interference of waves. The waves, the wave or disturbance, which travels from the water by the medium in which light travels as a wave? The answer is no! This is where the light is different from all other types of waves. You can travel through a vacuum, and does not require a means to advertise. How easy can it be? The answer lies in the fact that there are "waves" as the electromagnetic energy in it. Maxwell discovered how light passes through a vacuum. Any compiled object is the electric field with him when he has an electric field related to the theme changes, changes in the magnetic field. Then again, the magnetic field generates an electric field: This is how the electromagnetic waves, the light moves. Although the violation of travel, or waves in the electromagnetic field.

Visible light, radio waves and X-rays are electromagnetic waves that make up the electromagnetic spectrum! All are electromagnetic waves with different wavelengths and frequency, but all who travel the same speed, which is the light in a vacuum! Wavelengths of visible light spectrum is such that our eyes are such that a radio receiver is tuned to the radio waves! That is why our eyes can see that part of the electromagnetic spectrum.

Light travels straight in a vacuum. But in the medium term, has two characteristics of light reflection and refraction. When a wave of light can not penetrate the object is reflected back and when the light wave in the middle, which may be necessary, bent or broken. When light passes through the means of interaction with the electric field of the environment and, depending on the electric field, we can tell how much light is bent or broken. If you are interested, you can easily travel through the air, "the question has been answered. When traveling to the disturbance of the electromagnetic field. If you are interested in seeing the light traveling through the eye, then the answer is the same as in the air.

Only if the eye, the white light in the eyes, double, or break, is focused on your retina. Retina converts incident light into electrical signals that the brain creates an image that you see!
