1. Spot the difference between these images?
True colour image: Red, Green, Blue.
The Difference?
These two images are the same except this bottom image represents NIR (Near Infrared) wavelength. As you can see, vegetation appears bright red because it reflects NIR. NIR can not be seen by the human eye, however, satellite's can and therefore we are able to interpret and analyse images in wavelengths that we can not see.
