Q. Consider the following regarding infrared regions of the electromagnetic spectrum:
  1. Near Infrared
  2. Mid Infrared
  3. Far Infrared
Which of the following correctly represents the order of increasing wavelength?

Answer: 1,2,3
Notes: In the electromagnetic spectrum, Near Infrared has the shortest wavelength, followed by Mid Infrared, and then Far Infrared with the longest wavelength. Therefore, the correct order of increasing wavelength is: Near Infrared, Mid Infrared, Far Infrared (1, 2, 3).
