A structured infographic titled “The Electromagnetic Spectrum: Comparative Wave Properties (Radio vs. Optical)” compares radio spectrum and optical spectrum bands. Rows cover wave visualization, frequency, wavelength, energy, applications, propagation, technology, and detection, with illustrations of antennas, waves, prisms, lasers, phones, vision, and UV lamps. Blue radio-spectrum panels contrast with colored infrared, visible-light, and ultraviolet sections on a pale grid background.
