The electromagnetic spectrum is divided into various regions based on frequency and wavelength. When ranking these regions from highest to lowest frequency, the correct order is:
- Gamma rays
- X-rays
- Visible light
- Microwaves
- Radio waves
To elaborate:
- Gamma Rays: These have the highest frequency and are emitted by radioactive materials, making them powerful but also highly penetrating.
- X-rays: Slightly lower in frequency than gamma rays, X-rays are used in medical imaging due to their ability to penetrate soft tissues.
- Visible Light: This is the spectrum of light that human eyes can perceive. It stands in the middle of the spectrum.
- Microwaves: With a lower frequency than visible light, microwaves are often used in cooking and in communication technologies.
- Radio Waves: These have the lowest frequency in the electromagnetic spectrum and are widely used for broadcasting and communication.
Understanding this order helps in various applications, including medical imaging and communication technologies.
