Radio waves have no importance in and of themselves. The human species did OK
on Earth for many thousands of years without them.
But suddenly, within the past 100 years or so, we have allowed them to become
important in our lives, until now, most anyone in the civilized world would consider
himself to be seriously bummed if he could no longer use them.
Imagine yourself waking up tomorrow and finding out that you can't listen to
the radio, watch TV, make a cellphone call, send a text, heat your coffee in the
microwave oven, or use your GPS. Your wireless mouse, headphones, and
Bluetooth don't work, there is no WiFi in your house or at the coffeeshop, and
your garage door opener doesn't work. There is no satellite weather information,
it takes an hour to get a taxi, airplanes have to spend an hour in the pattern
before they can land, and any time you're stopped for seat belts, you have to
go downtown with the officer because he can't "run your plates".
I'd say that radio waves are pretty important today, mainly because we made them
important. Once again, we have met the enemy, and he is us.
What else can I help you with?
What electromagnetic wave have the lowest frequency?
Radio Waves.
What do baby monitors have to do with Electromagnetic waves?
The monitoring device is a radio transmitter that sends signals to the radio transmitter. Radio waves are a type of Electromagnetic waves.
What is the longest wavelengh in the electromagnetic spectrum?
The electromagnetic waves with the longest wavelength are called "radio waves". There is no limit to how long the wavelengths can be.
How are radio waves formed?
Radio waves are a type of electromagnetic radiation that are emitted by accelerating electric charges. When electrons within an antenna are oscillated or accelerated, they create electromagnetic waves at radio frequencies. These waves then propagate through space and can be received by devices like radios or antennas.
Are infrared rays electromagnet waves that are longer than radio waves but shorter than visible light rays?
Infrared waves are shorter than radio waves and longer than visible light waves.
Does mechinal waves have radio waves?
no, mechanical waves are not radio waves
How are electromagnetic waves different to radio waves?
Radio waves ARE electromagnetic waves.
Are radar waves visible?
No. Radar waves are one category of radio waves. Think of all the radio waves that are all around you right now . . . AM radio, FM radio, police and fire radio, highway patrol radio, taxi radio, television picture and sound radio waves, cellphone radio waves, garage-door-opener radio waves, bluetooth radio waves, WiFi waves, microwaves ... and you can't see any of them ! Radar waves can easily be there in the group.
Are radio waves transverse waves or longitudinal waves?
Transverse. Radio waves are electromagnetic waves, which are transverse.
What radio waves?
Radio waves are electromagnetic waves occurring on the radio frequency portion of the electromagnetic spectrum.
How are radio and television waves added to em radio waves?
by changing the amplitude or frequency of the radio waves.
When was Radio Waves - radio station - created?
Radio Waves - radio station - was created in 2010.
Why is the ionosphere important for communication?
It is what radio waves bounce off of.
How are radio waves and television signals added to EM radio waves?
by changing the amplitude or frequency of the radio waves.
Why the radio waves are similar to light waves but not sound wavesexplain?
Radio and light waves are electromagnetic waves, sound waves are not.
Radio waves do what to the radio so that we may heat them?
Radio waves are electromagnetic waves that carry energy. When these waves are absorbed by the radio's antenna, they induce electrical currents in the circuitry of the radio. This process allows the radio to convert the energy from the radio waves into sound, enabling us to hear broadcasts. However, radio waves themselves do not heat; it is the conversion of that energy into electrical signals that allows the radio to function.
What is a radio wave?
Radio waves are electromagnetic waves. The radio waves have the longest wavelengths in the electromagnetic spectrum. A radio wave has a much longer wavelength than does visible light. We use radio waves extensively for communications.
