How do radio waves carry the information? I mean the information is digital: 1 or 0, but what is 1 and what is 0 from perspective of radio waves?
Radio waves are a type of electromagnetic radiation that are used for transmitting information. They have a longer wavelength and lower frequency than other types of electromagnetic radiation, such as visible light.
Radio waves are used for communication by encoding information onto the waves through changes in amplitude, frequency, or phase. These encoded waves are then transmitted through the air and received by devices such as radios or cell phones.
Radio waves travel through space at the speed of light, which is approximately 186,000 miles per second. They can travel through a vacuum, such as outer space, as well as through different mediums, such as air or water.
Radio waves are used for information transition by encoding information onto the waves and transmitting them through the air. The receiving device then decodes the information to be understood by the user.
There is currently no scientific evidence to suggest that exposure to radio waves from devices such as cell phones or radios is harmful to human health. However, it is important to follow safety guidelines and limit exposure to high levels of radio frequency radiation.
