The characteristics of electromagnetic radiation are particularly important for understanding remote sensing:
|
|
Wavelength
|
|
|
Frequency
|
|
|
Wavelength and frequency
|
|
|
None of the above
|
Explanation:
Detailed explanation-1: -Two characteristics of electromagnetic radiation are particularly important for understanding remote sensing. These are the wavelength and frequency. The wavelength is the length of one wave cycle, which can be measured as the distance between successive wave crests.
Detailed explanation-2: -The behavior of EM radiation and its interaction with matter depends on its frequency, and changes qualitatively as the frequency changes. Lower frequencies have longer wavelengths, and higher frequencies have shorter wavelengths, and are associated with photons of higher energy.
