Description: A monochrome diagram displaying multiple Phon curves with labeled decibel sound pressure levels (dB SPL) on the y-axis and frequency in Hertz (Hz) on the x-axis. The graph features a barred frequency response with various curved lines representing different phon levels, such as 120, 960, 180, 900, and several instances of 'Phon'.

Description: The electromagnetic spectrum encompasses the full range of electromagnetic radiation, organized by wavelength or frequency. It includes radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays—each with unique properties and applications in communication, medicine, astronomy, and more. Despite their differences, all forms of electromagnetic radiation travel at the speed of light in a vacuum and consist of oscillating electric and magnetic fields.
