An atmospheric research probe measures four different electromagnetic signals, WWW, XXX, YYY, and ZZZ, emitted or reflected by the Earth's atmosphere. The characteristic wavelengths of these signals are:

  • W:2.0×10−2 mW: 2.0 \times 10^{-2}\text{ m}W:2.0×10−2 m
  • X:5.5×10−7 mX: 5.5 \times 10^{-7}\text{ m}X:5.5×10−7 m
  • Y:3.0×10−11 mY: 3.0 \times 10^{-11}\text{ m}Y:3.0×10−11 m
  • Z:8.5×10−6 mZ: 8.5 \times 10^{-6}\text{ m}Z:8.5×10−6 m

Which option correctly identifies the electromagnetic spectrum regions for these signals in order of increasing frequency?
