Electromagnetic radiation transports energy from point to point. This radiation propagates (moves) through space at 299,792 km per second (about 186,000 miles per second). That is, it travels at the speed of light. Indeed light is just one form of electromagnetic radiation. Some other forms of electromagnetic radiation are X-rays, microwaves ...

electromagnetic radiation. Therefore this radiation must be emitted in small packets, each containing DE. He then suggested that each energy of radiation will have its own frequency. Therefore he no longer thought of radiation from an object as continuous. He said it consisted of a series of "packets" of energy.

The consensus of the scientific community is that the power from these mobile base stations antennas is far too low to produce health hazards as long as the ...

infrared radiation. The operation starts by emitting a pulsed light beam from the transmitter and sending it back out to the scanning field. When the beam strikes an object, the infrared beam is interrupted. Thus, the light beam returns to the receiver with an angle after the reflection, then the receiver sends a high output signal.
