unpolarized light will have electric components and magnetic components that are pointing in all directions. The electric field and direction of travel of light must always be perpendicular. The electric field of an electromagnetic wave is what determines the polarization the wave It is not possible for the axis of polarization of light, and the direction of travel of said light, to be parallel. All objects are going to emit some amount of light, called thermal radiation, because they ...

What is the speed of light? - Light can travel enormous distances under short periods of time. It is faster than any other phenomenon. It takes about 8 minutes for light to travel from the Sun to Earth. The speed of light in a vacuum is c=3x10^8 m/s. Why is light such an important tool for astronomers? - Because light is how we learn about distant objects without travelling there. It is also a measuring took of astronomy. Light is a wave and a particle. How are different kinds of light wave...
