Remote sensing of vegetation characteristics is obtained by using:
(A) UV rays (B) Visible light (C) Microwave (D) Infrared rays
Choose the correct answer from the options given below:

Correct option is D

Remote sensing of vegetation characteristics is mainly performed using:
• Visible light (B): to capture reflectance in the red and green bands.
• Microwave (C): to penetrate clouds and capture canopy moisture.
• Infrared rays (D): especially near-infrared (NIR) are crucial for evaluating vegetation health (e.g., NDVI).
UV rays are not typically used for vegetation monitoring due to their limited penetration and reflectance properties.
