- A. Red Light
- B. X-rays
- C. Sound waves
- D. Photon
The Correct Answer is: C
Explanation
The answer is C. Sound waves.
Electromagnetic radiation consists of waves that travel together due to the interaction of electric and magnetic fields. The other options are all examples of electromagnetic radiation:
Red Light: This is a form of visible light with a longer wavelength and lower frequency on the electromagnetic spectrum.
X-rays: These are high-energy, high-frequency electromagnetic waves used for medical imaging and other applications.
Photon: This is the basic unit of light and other forms of electromagnetic radiation.
Sound waves, on the other hand, are mechanical waves that require a medium (like air or water) to travel. They consist of vibrations of particles in the medium and do not involve the interaction of electric and magnetic fields.
