A cell phone is a device that enables us to communicate with our friends and families. It enables us to receive radio links that is moving around a wide environment area. Nowadays there are millions of users all over the world who uses the phone. The first to invent phone was Martin Cooper in 1970’s. Nowadays phones are so advanced that it is used in many different ways. People use for downloading apps, playing games, texting people, calling friends etc. When we talk over the phone many types of radiation are given out like microwave radio waves etc.
There are two main types of radiation, ionizing and non-ionizing. The ionizing radiation is the energy is carried out by several types of ...view middle of the document...
This normally bumps an electron out of the atom, ionizing it. This electron then uses the energy it receives from the gamma ray to create additional ions by bumping electrons out of their atoms. A gamma ray is pure, it no longer exists once it loses all its energy.
There are different wave lengths in electromagnetic spectrum. This image shows the electromagnetic spectrum from the lowest energy/longest wavelength which is at the top of the image, to the highest energy/shortest wavelength which is the bottom of the image. Basically the radio waves have the largest wave length and gamma has the smallest. Radio waves are used by Cellular phones to pass on information from one phone to another. Because the phone uses microwaves which are created by a small antenna. Which means that the phone doesn’t have to be big. There are many types of electromagnetic radiation that makes up all the electromagnetic spectrum such as light, ultraviolet, x-rays and micro-waves. The microwave that we use to heat our food and the cell phones we use are part of the electromagnetic spectrum. The light that our eyes can see is also part of the electromagnetic spectrum. This visible part of the electromagnetic spectrum consists of the colours that we see in the rainbow- from reds and oranges, through blues and purples. The waves in electromagnetic spectrum vary in sizes from very long radio waves to the size of the buildings, to very short gamma-rays smaller than the size of the nucleus of an atom. Electromagnetic radiation is the stream of small quantity of light or electromagnetic energy, particles with no mass and no electric charge. Each of it travels in a wave and carries energy which moves at the speed of light. The radiation is known by the amount of energy found in the photons. Gamma-rays and X-rays are described in terms of energy which is measured in electron volts, radio in terms of frequency which is measured in hertz, and optical and infrared light in terms of wavelength which is measured in meters.
Type of Radiation in the Electromagnetic Spectrum
non- ionizing radiation is used in cell phones because of the heat, visible light , microwaves and radio waves that cell phones use are a form of non- ionizing radiation. There are two different types of radiation and they are ionising radition and non-ionizing radition which is shown in the picture above. Non- ionising radiation is different from ionising radiation because it does not create ions when it interacts with matter but lets out energy which is in the form of heat. The ionising radiation is energy which can be carried by lots of different types of particles and rays which is given off by radioactive material,x-rays machines and nuclear reactions. The picture above also shows the effects of both radiation types. Radio frequency waves are different from...
