Electromagnetic Waves Identification
Electromagnetic (EM) waves are a type of radiation made up of oscillating electric and magnetic fields. They travel at the speed of light and do not require a medium.
Analyzing Wave Types
- X-rays: These are a form of high-energy electromagnetic radiation, part of the EM spectrum.
- Beta rays: These consist of fast-moving electrons or positrons. They are particle radiation, not EM waves.
- Alpha rays: These are composed of alpha particles (helium nuclei). They are particle radiation, not EM waves.
- Audible waves: These are sound waves, which are mechanical waves requiring a medium like air or water to propagate.
Identifying EM Waves
From the options, only X-rays fit the definition of electromagnetic waves.
