When we examine the definition of a wave, we find a wave refers to the disturbance in a physical medium or field that results in an oscillation or vibration. The word “wave” often brings to mind our magnificent ocean waves. This is one reason why addressing climate change, and making choices to help create a sustainable future is important. Because of the Earth’s protective atmosphere, which absorbs gamma rays, we on the planet are protected from those harmful radiation waves. They operate at high frequencies, which means high energy is involved. The frequencies for UV, X-Ray and Gamma, which are outside the Visible Spectrum, are a harmful type of radiation to living organisms. Aside from LED light bulbs which sit inside the Visible Light Spectrum, you can listen to music over radio waves, your doctor performs x-rays to view broken bones, and you may have heated your lunch with the energy produced by the microwave spectrum. From low to high frequency range:Īll of these frequencies are present in your daily life. ![]() You will recognize many of the various regions of the EM Spectrum. The large range of frequencies within EM Radiation is a classification called the Electromagnetic Spectrum. What we can see is called the Visible Spectrum. The human eye cannot see all forms of electromagnetic radiation. Electromagnetic radiation helps with plant photosynthesis and with zooplankton biosynthesis in our oceans, it can be converted into solar power, and it allows us to see a variety of colors. An examination of the various forms of light can provide you with a solid base and understanding of light, as you create light plans for your current projects.Įlectromagnetic radiation is a form of energy. While scientists continue to debate about our world view or zeitgeist, there are a number of established principles and properties that can reveal the nature of light. It is a narrow band within the Electromagnetic Spectrum. ![]() As the name suggests, this is the segment the human eye can see. One aspect of light that is important to understand is the Visible Light Spectrum. ![]()
