1. Doppler radar systems provide information about the movement and position of targets. They work by sending a beam of electromagnetic waves at a specific frequency, at a moving object. When a microwave bounces off the object, its wavelength shifts as the object moves (this is known as the Doppler effect). The radar detects the shift and calculates how fast the object is traveling, along with it's location.
2. Polarized sunglasses block reflected light (glare). Since polarized light waves travel in a generally horizontal direction, the glasses have a special filter to block out this specific kind of wavelength, so only nonpolarized light can pass through!
3. When we see a rainbow, it is the result of the reflection and refraction of light waves. Light enters a water droplet and is refracted, then reflected by the back of the droplet. Reflected light waves leave the droplet, and are refracted again at many angles. The electromagnetic spectrum is made of light with many different wavelengths, and each is reflected at a different angle. The spectrum is separated, producing a rainbow of different wavelengths of visible length. Basically, the …show more content…
When the sun dips below the horizon, the sun is farther away from you than it was at noon. It has to travel through more atmosphere, then molecules and small particles in the atmosphere change the direction of light rays, making them scatter. Scattering changes the color of light coming from the sky by scattering the light, giving us sunsets.
4. When someone talks about the dual nature of electromagnetic waves, they're taking about how electromagnetic waves behave like both particles and waves. They travel like particles through a vacuum, and like waves through a medium. This means electromagnetic don't need a medium to travel, like every other kind of wave. The dual nature of electromagnetic waves was first proposed by Einstein.
