5.5. Technical Terms

Try these first

1. 1.

   Define the electromagnetic spectrum.

   Hint

   Think about the types of radiation that exist beyond just visible light.

2. 2.

   What is reflected energy in remote sensing?

   Hint

   What energy returns to a sensor after hitting an object?

3. 3.

   What does the electromagnetic spectrum encompass?

   • Only visible light
   • All types of EM radiation
   • Only infrared radiation

   Hint

   Remember that EMS includes both visible and invisible types of radiation.

4. 4.

   True or False: Reflected energy is the portion of EM energy absorbed by objects.

   • True
   • False

   Hint

   How does energy behave when it interacts with materials?

5. 5.

   Explain how understanding the electromagnetic spectrum can enhance the accuracy of remote sensing applications in agriculture.

   Hint

   Consider how specific wavelengths correspond to different plant properties.

6. 6.

   Discuss the implications of using different sensors on remote sensing platforms in marine versus terrestrial environments.

   Hint

   Analyze how environmental conditions change the requirements for sensors.
