Answer

Brief Explanations:

To determine how electromagnetic waves fight forest fires, we analyze each option:

  • Gamma rays are not used for forest fire hot spots (radioactive areas not relevant to fire).
  • Ultraviolet (UV) waves don't show fire hot spots as fluorescent (UV fluorescence is not for fire hot spots).
  • X - rays are for internal structures, not fire hot spots.
  • Infrared (IR) detects heat. Hotter areas emit more IR, so in IR images, hot spots (like in a forest fire) appear as red (or warmer - colored) areas, as IR imaging visualizes heat distribution.

Answer:

D. Infrared images can show hot spots as red areas.
