Let us make this perfectly clear: Don't look at the sun during a partial solar eclipse! Only during the few minutes of totality, when the sun's disk is completely covered by the moon, is it safe to view the eclipse with naked eyes.

Some wireless antennas transmit and receive EM waves whose polarization rotates 360 degrees with each complete wave cycle. This type of polarization, called elliptical or circular polarization, can be either clockwise or counterclockwise. The best communications results are obtained when the transmitting and receiving antennas have the same sense of polarization (both clockwise or both counterclockwise). The worst communications usually takes place when the two antennas radiate and receive in the opposite sense (one clockwise and the other counterclockwise).

REMEMBER: Looking directly at the sun, even when it is partially covered by the moon, can cause serious eye damage or blindness. NEVER look at a partial solar eclipse without proper eye protection.

Polarization is important in wireless communications systems. The physical orientation of a wireless antenna corresponds to the polarization of the radio waves received or transmitted by that antenna. Thus, a vertical antenna receives and emits vertically polarized waves, and a horizontal antenna receives or emits horizontally polarized waves. The best short-range communications is obtained when the transmitting and receiving (source and destination) antennas have the same polarization. The least efficient short-range communications usually takes place when the two antennas are at right angles (for example, one horizontal and one vertical). Over long distances, the atmosphere can cause the polarization of a radio wave to fluctuate, so the distinction between horizontal and vertical becomes less significant.

On April 8, a total solar eclipse will streak across North America, passing northeast from Mexico to Canada. Viewers in 15 U.S. states along the path of totality will have a chance to see the fully obstructed sun, while nearly every other state will see at least a partial solar eclipse. But no matter where you view the eclipse from, you need to do it safely. It's extremely dangerous to look at the sun, even if most of its light is obscured by the moon. Just as a magnifying glass can focus enough sunlight onto a leaf to start a fire, the lens in your eye can also focus that sliver of light onto your retina to burn it. And because retinas have no pain receptors, you can damage your vision without even feeling it happen.

Polarization, also called wave polarization, is an expression of the orientation of the lines of electric flux in an electromagnetic field ( EM field ). Polarization can be constant -- that is, existing in a particular orientation at all times, or it can rotate with each wave cycle.

Tape a small piece of white paper to the inside of the box, at the opposite end from the foil-covered hole. The paper should be positioned so that light entering the box through the pin hole will hit it. This is your "projection screen," where you'll look for the image of the sun.

Define polarizationin physics

Polarization affects the propagation of EM fields at infrared ( IR ), visible, ultraviolet ( UV ), and even X-ray wavelength s. In ordinary visible light, there are numerous wave components at random polarization angles. When such light is passed through a special filter, the filter blocks all light except that having a certain polarization. When two polarizing filters are placed so a ray of light passes through them both, the amount of light transmitted depends on the angle of the polarizing filters with respect to each other. The most light is transmitted when the two filters are oriented so they polarize light in the same direction. The least light is transmitted when the filters are oriented at right angles to each other.

Don't have a pair of eclipse glasses to view the April 8 total solar eclipse? No sweat; you can make a safe and simple DIY eclipse viewer with a box, some tinfoil, and a few household craft supplies.

Instead, NASA advises wearing a pair of approved solar eclipse glasses, or viewing the phenomenon indirectly through a handheld eclipse viewer. If you don't have any of those things on hand, don't stress; the best way to view an eclipse is through a simple pinhole camera, which can be made with materials lying around your house. Here's how.

To test your viewer, take it outside on a sunny day and hold the shoebox so that it lines up with its own shadow, aligning with light from the sun.

Stand so that when you look through the viewing hole, you can see a tiny circle of light on the image screen; that's the sun. During the eclipse, you'll see the shadow of the moon pass in front of the sun.
