5. Definition of Remote Sensing Remote sensing is the science and art of acquiring information (spectral, spatial, temporal) about material objects, area, or phenomenon, without coming into physical contact.

6. EMR In remote sensing, information transfer is accomplished by use of electromagnetic radiation (EMR).

17. Interactions between Matter and Electro-magnetic Radiation All matter reflects, absorbs, penetrates and emits electro-magnetic radiation in a unique way. For example, the reason why a leaf looks green is that the chlorophyll absorbs blue and red spectra and reflects the green spectrum
