Step 1: Understanding the Concept:
The question asks for the correct chronological sequence of events in the process of acquiring and using remote sensing data.

Step 2: Detailed Explanation:
The remote sensing process follows a logical flow from the energy source to the final information product:

The correct sequence of these stages is C $%5Crightarrow$ B $%5Crightarrow$ D $%5Crightarrow$ A.

Step 3: Final Answer:
The correct sequence is (C), (B), (D), (A).

Step 1: Understanding the Concept:
The question asks to arrange different types of electromagnetic radiation in the correct order as they appear in the electromagnetic (EM) spectrum. In the EM spectrum, wavelength and frequency are inversely related (higher frequency means shorter wavelength and higher energy). The standard convention is to list them in order of increasing wavelength or decreasing frequency/energy. Let's arrange them by decreasing energy.

Step 2: Detailed Explanation:
The order of the electromagnetic spectrum from highest energy/frequency (shortest wavelength) to lowest energy/frequency (longest wavelength) is:

Now let's place the given groups into this sequence:

Step 3: Final Answer:
The correct arrangement of the energy waves in the electromagnetic spectrum is (C), (D), (A), (B).
