REMOTE SENSING QUESTIONS WITH ACTUAL
ANSWERS
Electromagnetic Energy ✔️✔️Characterized by wavelength, frequency, amplitude, and phase.
Wavelength ✔️✔️Distance from one wave crest to the next.
Frequency ✔️✔️Number of crests passing a fixed point in a given period of time.
Remote Sensing Definition ✔️✔️Obtaining information about earth's surface from
measurements of radiated energy by aircraft or satellite sensors.
Atmospheric Windows ✔️✔️Refers to the parts of EMR spectrum that let EMR through
effectively, little interference, this makes Remote Sensing possible.
Atmospheric Correction ✔️✔️The process of removing the effects of the atmosphere on the
reflectance values of images taken by satellite or airborne sensors.
Amplitude ✔️✔️The equivalent to the height of each peak, often measured in energy levels or
watts.
