The electromagnetic (EM) spectrum encompasses all wave frequencies, including radio, visible light and X-rays. "Electromagnetic Spectrum." thinking why it is chosen to be named this way. Uses = radio frequency transmission/reception, x-rays, solar heating, light giving vision. Dangers: Extended gamma ray radiation can cause severe mutations or cancers in biological organisms--i.e. I used to get very tired after working with computer for 2 hours but wearing body shield, I could continue working on … We should wear UV blocking sunscreen on sunny days to avoid skin cancer. This happens as our bodies attempt to reduce the amount of ultraviolet radiation reaching deeper skin tissues. But we use objects and appliances that give off such energy. This section is not written yet. The properties dangers and applications of the varies waves on the em spectrum are in the table below. There is a wide range of subcategories contained within radio including AM and FM radio. They must also fill-in the names of some wave types that have been left blank. It doesn't mean that light (an example of electromagnetic wave) should be magnetic or electric. Radio waves are electromagnetic radiation, but they fall within the category of non-ionizing radiation, meaning they are longer and less energetic wavelengths. Visible light is the portion of the electromagnetic spectrum that is visible to the human … It took a bit longer for scientists to discover the higher-energy (shorter wavelength) light in the electromagnetic spectrum. Over-exposure to certain types of electromagnetic radiation can be harmful. There is concern that microwave radiation from mobile phones and masts may be harmful to our health. Let’s start with the most visible type of electromagnetic radiation: visible light … Aaron. They use ionizing radiation to penetrate any type of material. It ranges from extremely long wavelengths (extremely low frequency exposures such as those from power lines) to extremely short wavelengths (x-rays and gamma rays) and includes both non-ionizing and ionizing radiation. Electromagnetic wave means a wave that can propagate because of the periodic variation of the intensities of both the electric and magnetic fields.In other words, it means, when the intensities of the electric and magnetic fields change periodically, the wave can propagate. Microwaves have a standard measure of exposure, SAR (specific absorption rate) which is the rate of tissue energy absorption measured in watts per kilogram of tissue. The light we use to see, the microwaves that allow us to use our cells phones, the radio waves used to broadcast music to our cars, and the gamma rays used to treat cancer, are all the same waves varying only by wavelength and frequency. Any electronic device that operates within the radio frequency of the electromagnetic spectrum emits some radio waves, regardless of the presence of an antenna. The electromagnetic (EM) spectrum is the range of all types of EM radiation.Radiation is energy that travels and spreads out as it goes – the visible light that comes from a lamp in your house and the radio waves that come from a radio station are two types of electromagnetic radiation.
