Electromagnetic Spectrum Explained: Wavelengths, Frequencies & Real-World Scale #3276649 (License: Personal Use)

The image displays the electromagnetic spectrum from gamma rays (10⁻¹² m) to radio waves (10³ m), with corresponding frequencies (10²⁰ Hz to 10⁴ Hz), relative object scales (atomic nuclei to buildings), and blackbody temperatures where each radiation peaks. A color-coded visible light band highlights human vision range, while annotations indicate atmospheric penetration and real-world analogs like protozoans, butterflies, and humans.

Used in physics, astronomy, and earth science education to illustrate how different EM bands interact with matter and Earth’s atmosphere; supports learning about remote sensing, thermal imaging, and stellar classification.
