    Electromagnetic Induction The phenomenon called electromagnetic induction was first noticed and investigated by Michael Faraday, in 1831. Electromagnetic induction is the production of an electromotive force (emf) in a conductor as a result of a changing magnetic field about the conductor and is a very important concept. Faraday discovered that, whenever the magnetic field about an electromagnet was made to grow and collapse by closing and opening the electric circuit of which it was a part, an

    The Electromagnetic Spectrum [IMAGE] The electromagnetic spectrum is the entire range of radiant energies or wave frequencies. There are seven main regions in the electromagnetic spectrum. These are: radio waves, microwaves, infrared, visible light, ultraviolet, x-rays and gamma rays. Each section of the EM spectrum has a different wavelength, these are shown in the table below Section of EM spectrum Wavelength (in cm) radio waves > 10 microwaves 10 à 10 infrared

    The electromagnetic spectrum is made up of six different types of waves. Radio waves, Microwaves, Infrared waves, Visible light, Ultraviolet light, X-rays and Gamma rays. The radio waves are used to transmit radio and television signals. The infrared waves are used to tell temperature of areas. Visible light is all the colors that we can see. Ultraviolet light can help things grow but to much can cause diseases such as skin cancer. X-rays are used as a tool to find broken bones or take pitchers of

    Electromagnetic Radiation and Its Effect on the Human Body In 1998 a Maryland neurologist, Dr. Christopher Newman, was diagnosed with brain cancer and he could no longer work as a result of his disease. He claimed that the Motorola cell phone he had in 1992 to keep in touch with his patients gave him cancer. Then in 2000, he filed an $800 million lawsuit against several wireless providers including Motorola Inc., Verizon Communications Corp., Bell Atlantic Mobile Systems, and others. Within a month

    PART 1 The Electromagnetic Spectrum is the range of frequencies of possible electromagnetic radiation. The Spectrum ranges from 0 Hertz up to 2.4x1023 Hertz. The exact wavelength limits of the Spectrum are unknown however it is widely believed that the short wavelength limit is equal to the Planck Length (1.616x10-35m) and the long wavelength limit is the length of the Universe. Electromagnetic radiation (EMR) is an occurrence that takes the form of self-propagating waves produced by the motion

    The electromagnetic spectrum is the range of all electromagnetic radiation. The electromagnetic radiation can be radio waves that we use to listen to music, visible light that we use to see or microwaves that we use to cook food with. We deal with all of these types of radiations in our daily lives. RADIO WAVES: Radio waves are used exactly for what it says — radio. They are also the waves responsible for the signals cell phones and televisions receive. Objects in space, such as planets and comets

    The Electromagnetic Spectrum The electromagnetic spectrum is the collective name for all types of radiation. Radiation is energy that travels around in waves. The electromagnetic spectrum goes from the waves with the lowest energy to those with the highest energy. Radio Waves [IMAGE] Radio waves have the longest wavelengths in the electromagnetic spectrum. They can be from as long as a football to as long as a football pitches. Radio waves carry signals from devices from one place

    There are 7 different types of electromagnetic spectrums, which are Gamma rays, X-rays, ultraviolet rays, visible light, infrared, microwaves and radio waves. Each of them has their unique characteristics and if you use them carefully, it can be utilized to benefit people from many ways. In this essay, I will focus about Gamma rays, and Infrared lights. Gamma ray was first discovered in 1900 by French physicist Paul Villard. When Villard found Gamma rays, he recognized it is different from X-rays

    Introduction to light: Electromagnetic radiation is a form of light energy. Electromagnetic is made up from visible light, invisible light (ultraviolet, infrared, X-rays, radio waves and microwaves). In vacuum lights maximum velocity is 3.0x10^8 m/s. Reflection: If an object does not radiate its own light, it must reflect light to be visible. Reflection includes two beams - an approaching or incident beam and an active or reflected beam. The imaginary line that is perpendicular to the principal axis
