Electromagnetic waves section 2 the electromagnetic spectrum main idea different parts of the electromagnetic spectrum interact with matter in different ways section 3 using electromagnetic waves main idea electromagnetic waves are used to transmit and receive information looking through you this color-enhanced x-ray image of a human shoulder and ribcage was made possible by electromagnetic. Introduction contrary to popular belief, outer space is not empty space it is filled with electro- magnetic radiation that crisscrosses the universe this radiation comprises the spectrum of energy ranging from radio waves on one end to gamma rays on the other it is called the electromagnetic spectrum because this radiation is associat-ed with. Electromagnetic radiation is a form of energy released and absorbed by charged particles this radiation has specific electrical and magnetic properties the wavelength range corresponding to the electromagnetic radiation is termed the ‘electromagnetic spectrum’ the way in which the. 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 the other. Chapter 25 electromagnetic waves 251 the production of electromagnetic waves 252 the propagation of electromagnetic waves 253 the electromagnetic spectrum 255 polarization it was the great scottish physicist james clerk maxwell (1831-1879) who showed that electric and magnetic fields fluctuating together can form a propagating wave, appropriately called an electromagnetic wave. Introduction to electromagnetic waves light: electromagnetic waves, the electromagnetic spectrum and photons properties of electromagnetic radiation and photons google classroom facebook twitter email introduction to electromagnetic waves electromagnetic radiation is one of the many ways that energy travels.
Waves of the electromagnetic spectrum bms 8th grade these flashcards go with the astronomy flashcards unit 3 astronomy test: october 22, 2013 study play ___ is the energy that is transferred through space by the electromagnetic waves electromagnetic radiation the distance from the crest of one wave to the crest of the next wave is the ___ wavelength the number of waves. An introduction to the em spectrum going through each of the different types of waves with their frequencies, wavelengths, uses and dangers there is a bit in there about ionising and non-ionising radiation too. From a lamp in your house and radio waves that come from a radio station are two types of electromagnetic radiation other examples of em radiation are microwaves, infrared and ultraviolet light, x-rays and gamma-rays hotter, more energetic objects and events create higher energy radiation than cool objects only extremely hot objects or. The spectrum of electromagnetic waves is continuous from the longest wavelengths (radio waves) through to the shortest wavelengths (gamma rays) all electromagnetic waves are transverse waves that can travel through a vacuum they all travel through empty space at a speed of 300 000 000 m/s.
Electromagnetic spectrum measuring the electromagnetic spectrum you actually know more about it than you may think the electromagnetic (em) spectrum is just a name that scientists give a bunch of types of radiation when they want to talk about them as a group radiation is energy that travels and spreads out as it goes-- visible light that comes from a lamp in your house and radio waves. This continuous range of frequencies is known as the electromagnetic spectrum the entire range of the spectrum is often broken into specific regions the subdividing of the entire spectrum into smaller spectra is done mostly on the basis of how each region of electromagnetic waves interacts with matter the diagram below depicts the electromagnetic spectrum.
When an object is electro magnetic spectrum, it means that the object has absorbed or has a characteristic of electro magnetic radiation when measuring the frequency of electromagnetic spectrum, it depends on the length of the wave shorter the wavelength, the higher the frequency is going to be. Introduction 1 electromagnetic spectrum the electromagnetic spectrum is the distribution of electromagnetic radiation according to energy, fre-quency, or wavelength the electro-magnetic radiation can be described as a stream of photons, which are particles traveling in a wavelike pattern, moving at the speed of light. Understand that the sun's energy is transferred to earth by electromagnetic waves, which are transverse waves understand that there are eight main types of electromagnetic waves, classified on the electromagnetic spectrum according to their wavelengths understand how each of the types of. Students learn about the electromagnetic spectrum, ultraviolet radiation (including uva, uvb and uvc rays), photon energy, the relationship between wave frequency and energy (c = λν), as well as about the earth's ozone-layer protection and that nanoparticles are being used for medical applications.
Waves and electromagnetic radiation materials and resources radiation exposure: teacher background information vocabulary materials radiation types and sources worksheet (one per student, pair or group or group) electromagnetic spectrum image (included in the radiation exposure: teacher background information or the vocabulary materials) display with computer and projector radiation.

Introduction 1 electromagnetic spectrum the electromagnetic spectrum is the distribution of electromagnetic radiation according to energy, fre- quency, or wavelength the electro-magnetic radiation can be described as a stream of photons, which are particles traveling in a wavelike pattern, moving at the speed of. This startling coincidence in value led maxwell to make the inference that light itself is a type of electromagnetic wave maxwell's equations predicted an infinite number of frequencies of electromagnetic waves, all traveling at the speed of light this was the first indication of the existence of the entire electromagnetic spectrum. Introduction to electromagnetic waves maxwell’s equations: electromagnetic waves predicted and observed production of electromagnetic waves the electromagnetic spectrum energy in electromagnetic waves geometric optics introduction to geometric optics the ray aspect of light the law of reflection the law of. List the main types of electromagnetic waves in order of increasing frequency radio waves, microwaves, infrared, visible light, ultraviolet light, gamma rays, x-rays.
