The purpose of this illustration is to show that the electromagnetic radiation emitted by the sun passes through the atmosphere and is reflected at the surface. The radiation is reflected by the ground through the atmosphere and is captured and recorded on the satellite remote sensor. The satellite transmits the data to both a relay satellite or to a receiving station on the ground. Once the data is received on the ground, the data is processed and enhanced by a computer, sorted, analyzed, and/or printed on paper for various applications.
The purpose of this illustration is to show the relationship between the direction of propagation of an electromagnetic wave and the direction of its electric and magnetic fields. Electric and magnetic fields are perpendicular to each other, and are perpendicular to the propagation direction.
The purpose of this illustration is to show the relationship between the frequency and wavelength of an electromagnetic wave. The diagram shows three oscillating waves at different frequencies, and the three wavelengths associated. Note that the shorter the wavelength, the higher the frequency and vice versa.
C equals lambda times v, where lambda is the wavelength in meters, v is the frequency in cycles per second, and c is the speed of light, or three times ten to the power of eight meters per second.
C equals lambda times v. Three multiplied by ten to the power of eight equals lambda times, open bracket, five hundred thousand multiplied by ten to the power of nine, close bracket. Three multiplied by ten to the power of eight equals lambda multiplied by, open bracket, five multiplied by ten to the power of fourteen, close bracket. Three multiplied by ten to the power of eight divided by five times ten to the power of fourteen equals lambda. Six multiplied by ten to the power of minus seven meters equals lambda.
