Explanation / Answer

use Dark Subtraction is worn to take away the belongings of impressive spreading as of the picture by take away a pixel value that represent a setting spreading from every band. We will be with the group minimum principles we research and wrote down in Step 12.

The x band has the shortest infrared because it has the longest wave lenghth in the given table values.
