There are several regions of the electromagnetic spectrum which are useful for remote sensing. The focus of this presentation is the ELECTROMAGNETIC SPECTRUM. 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 electromagnetic spectrum is a continuous range of wavelengths. Presentation Summary : electromagnetic spectrum. The light we can see, made up of the individual colors of the rainbow, represents only a very small portion of the electromagnetic spectrum. Gamma rays As the wavelengths of electromagnetic waves get shorter, their energy increases. Light waves are given off by anything that's hot enough to glow. • Frequency is measured in cycles per second (Hertz or Hz or kHz), • Wavelength is measured in meters (m) or nanometers (nm). Originally created in 1944 as a wall-sized poster distributed by the W.M. And even then, you're likely to return for more. Electromagnetic Spectrum Presentation.
