RADIO WAVES

Explanation:

All telecommunication is done with the help of electromagnetic waves.

We have to choose that part of electromagnetic range which will have less energy so that it is not harmful for the humans

As we arrange all electromagnetic waves in decreasing order of energy then it is as following

1. Gamma Rays

2. X Rays

3. Ultraviolet Rays

4. Visible light

5. Infrared waves

6. Microwaves

7. Radiowaves

So for safety purpose all the telecommunication is done with the help of radio waves.

Electricity may be categorized as static or current. how are these two types of energy different

arlik [135]

Hello!

Static electricity occurs due to an imbalance in positively and negatively charged atoms. An example of this is when you take your clothes out of the dryer, and feel a slight sting when touching them. Another example of static electricity is lightning.

Current electricity occurs when there is a constant flow of electrons, such as in plug-operated machinery or anything operated using a battery. :)
