2.4.1. Reflection, Absorption, and Transmission

Try these first

1. 1.

   Define reflection in the context of remote sensing.

   Hint

   Think about how light behaves when it hits a mirror.

2. 2.

   What is absorption?

   Hint

   Consider how plants utilize light energy.

3. 3.

   What is reflection in the context of remote sensing?

   • Energy absorbed by a surface
   • Energy passing through a surface
   • Energy bouncing back from a surface

   Hint

   Consider how you see yourself in a mirror.

4. 4.

   Is absorption a process that involves taking in energy?

   • True
   • False

   Hint

   Think about how plants use sunlight.

5. 5.

   Consider a wetland area with different types of vegetation and water bodies. How can each process (reflection, absorption, transmission) be used to determine the health of the ecosystem?

   Hint

   Think about how you would analyze an image to understand plant conditions and below-surface properties.

6. 6.

   You are tasked with creating a remote sensing strategy for analyzing urban growth. Which interactions (reflection, absorption, transmission) will you prioritize and why?

   Hint

   Consider all the surfaces you see and their different roles in urban geography.
