Question

compare the reception of messages using different materials​

Answer 1

Answer:

Radio waves are a type of electromagnetic radiation, a kind of energy that also includes visible light. Radio waves are not harmful but are in fact extremely useful for communicating across long distances. To send information using radio waves, a transmitting antenna sends out a radio wave at a certain frequency (which can tell us the size of the wave), and this is picked up by a receiving antenna. Some materials can block, or interfere with, radio waves. Have you ever noticed that you lose reception on a car radio or cell phone when you drive into a tunnel

Answer 2

Answer:

A form of electromagnetic radiation that also contains visible light is radio waves. Radio waves are highly helpful for communicating across great distances and are not damaging at all.

Explanation:

Given:  The reception of messages using different materials​

To find:   Compare the reception of messages using different materials​

Step 1: Nonconducting materials like wood, bricks, and concrete can be fairly effectively penetrated by radio waves. They cannot cross metals or water, which are electrical conductors.

Step 2:Because copper can absorb both magnetic and radio waves, it is the most dependable material for shielding against radio frequencies. Additionally, it is very effective at weakening electrical and magnetic waves.

Step 3: Some materials have the ability to block radio frequencies. Some materials can let radio waves flow through them. The material encasing the remote control has the potential to degrade the signal.

Step 4: Every atom has an electron shell, as you are aware. These electrons communicate with one another and with the outside environment. The characteristics of these electrons determine whether or not a particular type of incoming electromagnetic wave will pass through.
