Manmade radio waves are generated when electrons, which are negatively charged, move back and forth within an antenna. This movement of charged particles creates a field that radiates out from the antenna at the speed of light and the radio wave is the safest wave has a low frequency
Microwaves can be used to cook our food or can be used as satellites for radar and they can see through, light rain, snow clouds, and smoke it can be used for looking at earth from space it is also a safe type of wave and has a low frequency.
Infrared light lies between the visible and microwave portions of the electromagnetic spectrum. Infrared light has a range of wavelengths, just like visible light has wavelengths that range from red light to violet. "Near infrared" light is closest in wavelength to visible light and "far infrared" is closer to the microwave region of the electromagnetic spectrum. The longer, far infrared wavelengths are about the size of a pin head and the shorter, near infrared ones are the size of cells, or are microscopic. It can also be thermal so if you have an infrared camera then you can see people's body heat. It is a safe wave and it has a low frequency
Visible light waves are the only electromagnetic waves we can actually see with our own eyes. We see the colors of rainbows each color has a different wavelength. Red has the longest wavelength and violet has the shortest wavelength. When all the waves are seen together, they make they make light When white light shines through a prism, the white light is broken apart into the colors of the visible light spectrum. Water vapor in the atmosphere can also break apart wavelengths creating a rainbow. The visible light is kind of in the middle of safe and dangerous but it has high frequency
Ultraviolet (UV) light has shorter wavelengths than visible light. Though these waves are invisible to the human eye, some insects, like bumblebees, can see them. Scientists have divided the ultraviolet part of the spectrum into three regions: the near ultraviolet, the far ultraviolet, and the extreme ultraviolet. The three regions are distinguished by how energetic the ultraviolet radiation is, and by the "wavelength" of the ultraviolet light, which is related to energy. We use ultraviolet is dangerous and has a high frequency and we can use autonomy to help see it without is being dangerous.
As the wavelengths of light decrease, they increase in energy. X-rays have smaller wavelengths and so higher energy than ultraviolet waves. We usually talk about X-rays in terms of their energy rather than wavelength. This is because X-rays have very small wavelengths. It is also because X-ray light tends to act more like a particle than a wave. X-ray detectors collect actual photons of X-ray light - which is very different from the radio telescopes that have large dishes designed to focus radio waves. we can use X-rays by if someone thinks they have gotten a very bad sprained ankle or a broken bone they go to the doctor and they do an x-ray also they do that at the dentist to see how your teeth are doing. It has high frequency and is very dangerous.
Gamma-rays have the smallest wavelengths and the most energy of any other wave in the electromagnetic spectrum. These waves are generated by radioactive atoms and in nuclear explosions. Gamma-rays can kill living cells, a fact which medicine uses to its advantage, using gamma-rays to kill cancerous cells. Gamma-rays are the most energetic form of light and are produced by the hottest regions of the universe. They are also produced by such violent events as supernova explosions or the destruction of atoms, and by less dramatic events, such as the decay of radioactive material in space. Things like supernova explosions (the way massive stars die), neutron stars and pulsars, and black holes are all sources of celestial gamma-rays. The Gamma-ray is the most dangerous wave off them all with a very high frequency and a very dangerous.
