Fundamentals of Remote Sensing
Most active sensors operate in the microwave portion of the electromagnetic spectrum which makes them able to penetrate the atmosphere under most conditions and can be used day or night Have a variety of applications related to meteorology and observation of the Earth\'s surface and atmosphere |

What is electromagnetic spectrum?
The electromagnetic spectrum is simply the full range of wave frequencies that characterizes solar radiation. Although we are talking about light, most of the electromagnetic spectrum cannot be detected by the human eye. Even satellite detectors only capture a small portion of the entire electromagnetic spectrum. What is Remote Sensing?
What were the applications of electromagnetics in the 20th century?
During the twentieth century vacuum tubes, diodes, transistors, integrated circuits, lasers, and superconductoed the capabilities and rs all vastly extend applications of electromagnetics.
What are the applications of electromagnetic field analysis?
Chapter 3: Electromagnetic Fields in Simple Devices and Circuits 3.1 Resistors and capacitors 3.1.1 Introduction One important application of electromagnetic field analysis is to simple electronic components such as resistors, capacitors, and inductors, all of which exhibit at higher frequencies characteristics of the others.
How does electromagnetic energy travel?
Electromagnetic energy travels in waves and spans a broad spectrum from very long radio waves to very short gamma rays. The human eye can only detect only a small portion of this spectrum called visible light. A radio detects a different portion of the spectrum, and an x-ray machine uses yet another portion.
Overview
This article is about the Electromagnetic energy and its uses. It explains how electromagnetic energy travels in waves, spans a broad spectrum from radio waves to gamma rays, and how NASA's scientific instruments use it to study the Earth, solar system and universe beyond. The article also mentions that our atmosphere protects us from exposure to h
Electromagnetic Energy
Electromagnetic energy travels in waves and spans a broad spectrum from very long radio waves to very short gamma rays. When you tune your radio, watch TV, send a text message, or pop popcorn in a microwave oven, you are using electromagnetic energy. You depend on this energy every hour of every day. Without it, the world you know could not exist. science.nasa.gov
Sun & Atmosphere
The Earth's atmosphere protects us from exposure to harmful higher-energy waves that can be ionizing and cause damage to cells in organic matter but is not helpful when studying sources of high-energy radiation in space as instruments have to be positioned above Earth's atmosphere. science.nasa.gov
Beyond our Atmosphere
NASAspacecraft provide scientists with a unique vantage point helping them "see" at higher-energy wavelengths that are blocked by the Earth's protective atmosphere while some microwaves can even pass through clouds making them best for transmitting satellite communication signals. science.nasa.gov
