Nonparticulate radiation spans a wide range of energies, categorized by their wavelength and frequency:
Used for communication (cell phones, Wi-Fi) and heating food. What is Radiation? - International Atomic Energy Agency nonparticulate radiation
Lower-energy waves that lack the power to ionize atoms but can cause thermal effects. Nonparticulate radiation spans a wide range of energies,
Nonparticulate radiation lacks mass and charge, existing purely as "packets" of energy called photons. nonparticulate radiation
The only part of the spectrum detectable by the human eye. Infrared (IR): Experienced as heat.
