Though the sciences generally classify EM waves into seven basic types, all are manifestations of the same phenomenon. This is how light bulbs work - an electric current heats the lamp filament to around 3,000 degrees, and it glows white-hot. These waves can be as long as a mile. Which electromagnetic wave type has the smallest wavelength? Similar to the UV spectrum, the infrared spectrum is invisible to the naked eye, however since the region is closer to the red region of the visible spectrum, it is known as the infrared region. They can penetrate soft tissue like skin and muscle and are used to take X-ray pictures of bones in medicine. 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. List them from left to right.

X-rays have wavelengths ranging from about 10-8 m or 10 nm to 10-13 m or 10-4; X-rays are particularly well known due to their use as a diagnostic tool in medicine. In the electromagnetic spectrum, X-rays lie beyond the ultraviolet region. The human eye can only detect only a small portion of this spectrum called visible light. FREE (41) russellarnott … The electromagnetic (EM) spectrum encompasses all wave frequencies, including radio, visible light and X-rays. On the spectrum further up the page, I have shown the ultra-violet and the infra-red, but this can be extended even further into x-rays and radio waves, amongst others. Light waves are given off by anything that's hot enough to glow. ZIP (370.96 KB) Introducing the electromagnetic spectrum? In fact, most of the light in the universe is invisible to our eyes. We call this range of colours the visible spectrum, however, this is only a small part of a very much longer spectrum called the electromagnetic spectrum. 25. Includes clean animations, gifs, and great videos to help students understand how the electromagnetic spectrum is used to discover and observe component magnetic field electric field wave direction They are all different types of electromagnetic radiation that travel as waves and transfer energy from the source of the waves to an absorber. Presentation Summary : electromagnetic spectrum. X Rays Electromagnetic Spectrum Song EM wave is a disturbance that involves transfer of electric and magnetic energy-aka a movement of charged particles which have electric and magnetic fields around them. 2. Waves in the spectrum White light can be split up into lots of different coloured light waves using a prism. Waves "R" Us Images Visible light The only electromagnetic radiation to which human eyes are sensitive to. This is an inverse relationship between wave size and frequency. Wave Activity Pick a Wave TIMER: 5 MIN. 5. The electromagnetic spectrum is a continuous range of wavelengths. Originally created in 1944 as a wall-sized poster distributed by the W.M. Also, the treatment for certain types of cancer involves the use of X-rays. The electromagnetic spectrum is the range of frequencies (the spectrum) of electromagnetic radiation and their respective wavelengths and photon energies. There are several regions of the electromagnetic spectrum which are useful for remote sensing. Their different frequencies gives us different colors Infrared The word color refers to the light of a The electromagnetic spectrum doesn't stop with the colours you can see. As you go from left right, the wavelengths get smaller and the frequencies get higher. 1] Infrared Spectrum (IR Spectrum) – If we move to the right of the visible spectrum, there would lie the infrared spectrum region. $3.00. Images They make up less than 1millionth% of electromagnetic spectrum. The focus of this presentation is the ELECTROMAGNETIC SPECTRUM. Electromagnetic Spectrum Presentation. 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.
