We generally think of radio waves (radio electromagnetic radiation) as those frequencies of electromagnetic (EM) radiation that fall within a band of frequencies below those of light. These include microwave bands, on which satellites communicate and cell phone operate, as well as the familiar microwave oven. Radar also operates in this band. Below that we find television signals, as well as some two-way radio signals. Other forms of communications radio signals (like amateur or "ham" radio) as well as broadcast radio operate below the television bands.
By considering the types of equipment mentioned above, it is possible to make a list of some sources of radio electromagnetic radiation.
they use radio waves to pick up some what satellite images or existance of things in space
Radio waves are in all parts of the atmosphere. Some, but not all, radio waves are reflected from the ionosphere, permitting transmission over greater distances.
for wavelength, the longer of the two is visible light, but the longest type of rays are radio waves (some of them have a wavelength as long as a football field)
'Radio' waves are physically and electrically identical to light waves except for their frequency (wavelength), and they travel at the same speed as light does.
Radio waves aren't harmful at its usual pattern of operation. They are harmful only when a strong signal is close to a person. It can cause cancer and other problems. Radio waves may also cure. All waves have different results.

False. For some bands of radio waves the atmosphere is transparent. Radio waves can penetrate to the ground. That's why we have radio telescopes on the Earth.
Radio waves are used in everyday life for communication and entertainment. Common applications of radio waves in modern technology include cell phones, Wi-Fi, GPS, and radio broadcasting.
ELF radio waves or extremely low frequency radio waves. These may have frequencies below 1 Hz in some cases!

radio waves, microwaves, visible light, and x-rays
Quasar actually means quasi-stellar radio sources so we thought that it was giving off radio waves but we did not put into account the redshift that causes the stretching of the wavelength meaning that it most likely gives off microwaves.
Natural sources for americium doesn't exist.
Water is not a wave. Waves on a water surface, on the other hand, do indeed have similarities with other types of waves in physics, including radio waves.

Exposure to radio waves from devices like cell phones and Wi-Fi routers has been linked to potential health risks such as headaches, fatigue, and sleep disturbances. Some studies suggest a possible connection to cancer, although more research is needed to confirm this. Radio waves can be harmful to humans by potentially disrupting the body's natural electromagnetic fields and causing cellular damage. It is important to limit exposure to radio waves and use devices responsibly to minimize any potential health risks.
