ScienceAid QnA. Overexposure of our eyes to ultraviolet radiation can cause blindness, so we should wear hats and sunglasses on sunny days. The electromagnetic spectrum is the range of all frequencies of electromagnetic radiation which includes visible light as well as invisible radiations like radio waves, infrared rays, gamma rays. With the proliferation of cell phones, wireless Internet, and personal electronic devices, the ill effects of electromagnetic radiation are a huge concern. Any electronic device that operates within the radio frequency of the electromagnetic spectrum emits some radio waves, regardless of the presence of an antenna. 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. Uses = radio frequency transmission/reception, x-rays, solar heating, light giving vision. ScienceAid QnA. This section is not written yet.

Year 10 Electromagnetic Spectrum – Uses and Dangers. Just a curious mind. They use ionizing radiation to penetrate any type of material. What order do waves length go in and in what order of length? 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. We cannot see or feel ultraviolet radiation, but our skin responds to UV exposure by turning darker over time. The main risks associated with electromagnetic waves are summarised below: Further notes: Microwaves: Applications and Dangers of Electromagnetic Waves - YouTube They should include the uses and dangers of each type of radiation, and can create their own mnemonic. Parts of the electromagnetic spectrum of thermal radiation may be ionizing, if the object emitting the radiation is hot enough (has a high enough temperature). 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. This spectrum includes many types of wave that you will recognize including X-rays and infra-red. Students can use the chart they created as review, and this activity can be completed at the beginning or the end of a unit. of the radiation, the more damage it is likely to cause to the body: radiation is felt as heat and causes skin to burn, damage cells causing mutations (which may lead to cancer) and cell death - this is why doctors and dentists stand behind protective screens when taking lots of X-rays, also damage cells causing mutations and cell death. There is a wide range of subcategories contained within radio including AM and FM radio. Large doses of radio waves can cause cancer, leukaemia and other disorders. It doesn't mean that light (an example of electromagnetic wave) should be magnetic or electric. All EM waves are made up of photons that travel through space until they interact with matter; some waves are absorbed and others are reflected. In terms of frequency, this corresponds to a band in the vicinity of 430–770 THz. Sign in, choose your GCSE subjects and see content that's tailored for you. Microwaves are radio waves, and their frequencies can range anywhere from 300 MHz (300 million cycles per second) to 3 GHz.RF. The visible light spectrum is the portion of the electromagnetic spectrum that we know the best. In electromagnetic spectrum, radio window is extended from about 15 MHz (wavelength of about 20 meters) to 30 GHz (wavelength of about 1 cm). Uses and dangers of electromagnetic radiation Interact with different objects to find out how electromagnetic radiation is used outside of the lab. Would you like to give back to the community by fixing a spelling mistake? Electromagnetic Spectrum.

In ScienceAid. Hello I'm Jamie too and I have a question please and thank you That’s why you can use radio telescopes from the ground to study while for other frequencies it is necessary to construct and send special telescopes in space as satellites. The properties dangers and applications of the varies waves on the em spectrum are in the table below. 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. In fact, too much of any radiation can make this happen, even those helpful X-rays. Visible Light Waves. "Electromagnetic Spectrum." Visible Light. This happens as our bodies attempt to reduce the amount of ultraviolet radiation reaching deeper skin tissues. Advanced; Basic; The Electromagnetic Spectrum. reaches the deeper tissues.

Longest wavelength and lowest frequency starts Radio waves, microwaves, infrared, visible light, ultraviolet light, x rays, gamma rays There are certain types of electromagnetic radiation that can be harmful to us. In general, electromagnetic waves get more and more dangerous the shorter their wavelength: Radio waves have no known harmful effects whilst gamma rays can cause cancer and are regarded as extremely dangerous. This is called "Radiotherapy", and works because healthy cells can repair themselves fairly well when damaged by gamma rays - but cancer cells can't.Getting the dose right is very important! This is called a sun tan. Uses and Dangers of the Electromagnetic Spectrum Being prone to lots of UV waves can damage the retina in your eyes, so make sure your sunglasses protect against UV. us humans.

The three main types of ultraviolet radiation and some of their effects, Causes severe sunburn and damage to cells, Home Economics: Food and Nutrition (CCEA). Ultraviolet radiation - UV - is found naturally in sunlight. Mutations in cells and severe burns to the skin. Radio waves are electromagnetic radiation, but they fall within the category of non-ionizing radiation, meaning they are longer and less energetic wavelengths. Dangers Large doses of radio waves are believed to cause cancer , leukaemia and other disorders. Darker skins absorb more ultraviolet light, so less ultraviolet radiation reaches the deeper tissues. Electromagnetic radiation from the spectrum has found multiple applications ranging from communication to manufacturing. Electromagnetic waves form a spectrum of different wavelengths.
