1
The Electromagnetic Spectrum
Standard 8-6.8 Compare the wavelength & energy of waves in various parts of the electromagnetic spectrum.
2
Electromagnetic Spectrum
Electromagnetic waves have what? What is the electromagnetic spectrum? a wide range of wavelengths the entire range of wavelengths the relationship between the wavelength & energy of waves in various parts
4
Visible Light What is visible light?
What is the visible light spectrum? Where are the wavelengths of visible light? The longer the wavelength the range of electromagnetic waves that can be detected by the human eye entire range of visible light the middle range of the wavelengths/frequencies of electromagnetic waves the lower the energy of the wave is
5
What Color do I See? the human eye reacts to different energies & frequencies of light in the visible light spectrum colors toward the blue-violet range & have higher energy colors toward the orange-red range & have lower energy How is it that different colors are seen? Higher frequencies (shorter wavelengths) are perceived as what colors? Lower frequencies (longer wavelengths) are perceived as what colors
6
Infrared Radiation the range of electromagnetic waves with frequencies lower than red on the visible light spectrum, thereby having longer wavelengths & less energy than red wavelengths but hotter objects emit more infrared radiation than cooler infrared rays they become warmer What is infrared radiation? All objects emit infrared radiation… Heat energy is transmitted by what? When objects absorb infrared radiation…
7
Ultraviolet Radiation
the range of electromagnetic waves with frequencies higher than violet on the visible light spectrum, thereby having shorter wavelengths & more energy then violet wavelengths too much exposure is damaging to the eyes & the skin What is ultraviolet radiation? Because of the high energy of ultraviolet radiation…
