Pretend there is a patient and the doctors need to see deep into his body, in a safe way. To start off, they use the MRI, which uses the radio waves to construct a computer image (of the tissue, they are looking at). The MRI device sends a short bursts of radio waves into the paitients body. The radio waves energize atoms (energize the patients particles inside his body)and make them line up. When the radio pulses are turned off the atoms return to there original position and the radio waves return to the machine (when the radio waves come back to the machine or when they return, the machine now has the picture of the tissue).
It is kind of like a delivery man or getting your picture taken. For example, the delivery man... at first it is like a shock you get mail, then when it is done the delivery man leaves. He goes and deliveries it to someone else. So, then that person just recieved whatever you sent. Just like the machine, the machine just got whatever the radio waves gave it... the picture of the tissue.
Radio waves can be used to determine the position of icebergs at sea using radar systems. Radar emits radio waves that bounce off the iceberg and return to the system.
it hits the iceberg.. i think
no, mechanical waves are not radio waves
Radio waves ARE electromagnetic waves.
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.
Radio waves were discovered before the radio was invented.
Radio waves and cell phones
Radar locates objects with radio waves.

A dish antenna must face the arriving waves.

Radio waves are transverse waves. This means that the oscillations of the waves are perpendicular to the direction of energy transfer.
Radio waves can be blocked or attenuated by physical barriers such as thick walls, metal objects, or dense materials like concrete. The level of attenuation depends on the material and thickness of the barrier. In general, the higher the frequency of the radio wave, the more easily it can be blocked.
Radio waves ARE electromagnetic waves.
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.
This is likely describing the process of using radar technology to determine the position of a solid object. Radar works by emitting high-frequency radio waves towards an object and then measuring the time it takes for the waves to reflect back, allowing for calculations of the object's distance and position.
by changing the amplitude or frequency of the radio waves.
Radio waves are electromagnetic waves occurring on the radio frequency portion of the electromagnetic spectrum.
