After the message is boosted at a cell tower‚ state two different ways the message may be sent to the receiving mobile phone. If you are far away from the person the electromagnetic or microwaves are converted in to light energy transmitted through optic fiber cables in the land base telephone systems‚ the signal is boosted and sent to another cell tower closest to the receiving mobile phone. That tower then sends the signal

(Part 2) – Negative Health Effects [Cell] phones transmit and receive Radio Frequency (RF) signals in order to communicate. The RF signals from [cell] phones fall within the microwave part of the electromagnetic spectrum. This radiation is also referred to as microwave radiation or electromagnetic radiation. In short: Cell phones use microwave radiation to communicate. Cell Phone Disadvantage #2 – Negative Health Effects Most media reports would have you believe that research studies

telescopes utilize one or more concave mirrors for the objective lens to condense the light and a small lens called an eyepiece. Pg3 Conclusion A telescope is an instrument that aids in the observation of remote objects by collecting electromagnetic radiation (such as visible light). The first known practical telescopes were invented in the Netherlands at the beginning of the 17th century‚ using glass lenses. They found use in terrestrial applications and astronomy. Within a few decades

Sometimes radiation cannot be controlled or contained and accidents take place causing radiation leaks. For this reason‚ protocols and radiation safety has become a pre-curser in our everyday life.
