    is a form of electromagnetic radiation. Electromagnetic radiation is energy letting out waves like behaviour as it is travelling through space. Examples of electromagnetic radiation are microwaves, x-rays and visible light. The electromagnetic spectrum consists most of the colours we world normally see in a rainbow colours like red, orange, green, yellow, blue, indigo and violet. When we put our cell phones into our pocket or anywhere near our body we are letting a lot of radiations enter into our

    Ezra Williams 14199844 Mr. Frank Marziani 1/26/17 Experiment 1 Spectroscopy Introduction Spectroscopy studies the reciprocal action of electromagnetic radiation with matter. In spectroscopy, the energy amounts needed to move an electron into another orbit is measured by the differences of energy. The Bohr model of the atom is a theory of an atoms atomic structure. According to Bohr, the electron is said to be moving around the nucleus in a fixed orbit. This theory was based on the attractive

    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

    The electromagnetic spectrum is all around us and serves many beneficial and lifesaving purposes every day. There is no escaping it, because much of the spectrum cannot be seen. We can tell it has taken place by getting a tan or sunburn or by the fact that our plants and flowers thrive and grow. This includes x-rays, gamma rays, visible, ultraviolet, infrared light, radio waves and microwaves. While it has many useful purposes, it can also have many negative consequences due to overexposure, some

    Introduction to light: Electromagnetic radiation is a form of light energy. Electromagnetic is made up of 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

    is electromagnetic energy also known as electromagnetic radiation (EMR) that we are surrounded by every day, emitted from natural sources like the sun, earth and the ionosphere. It is also emitted from unnatural sources like mobile phone base stations, broadcast towers, radar equipment, remote controls, electrical and electronic equipment. Electromagnetic radiation travels in waves. There are many types of electromagnetic waves which differ in the wavelength. These electromagnetic radiations form

    potential health hazard. While their health effects are largely untested, there have been numerous studies of the effects of the electromagnetic radiation emitted from these devices. All scientists agree that this radiation is dangerous at high levels and new studies are beginning to suggest that they may pose health risk at lower levels as well.("Wi-Fi Health Dangers & Radiation Health Effects") U.S. Citizens enjoy the many conveniences associated with wireless devices, yet we deserve adequate protections

    Introduction: Key Concepts: Light as a form of electromagnetic radiation: Light can be classified as a form of electromagnetic radiation, which includes visible light. The ‘light’ commonly referred to in everyday life belongs in this category. The electromagnetic spectrum includes other types of radiation such as gamma rays, radio waves and cosmic rays, all of which possess distinct wavelengths, frequencies and energy levels. These forms of electromagnetic radiation are not visible to the human eye but can
