Answer 1

10. Surrounding us and everywhere we go is the radio spectrum.

11. Waves that have the lowest energy and longest wavelength are radio waves.

12. The shortest, highest energy waves in the electromagnetic spectrum are gamma rays.

13. Our eyes are able to view energy of wavelengths with 400 - 700 nanometers called: visible light.

The electromagnetic spectrum encompasses a wide range of electromagnetic waves, each characterized by distinct wavelengths and frequencies. This spectrum includes radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays. These waves cover an extensive range of wavelengths, from kilometers for radio waves to picometers for gamma rays.

Radio waves, with wavelengths around
`\(10^3\)` meters, are used for communication and broadcasting. Microwaves, with wavelengths of
`\(10^(-2)\)` meters, find applications in technologies like radar and microwave ovens. Infrared radiation, with wavelengths of
`\(10^(-5)\)` meters, is associated with heat and is used in night vision devices.

Moving towards shorter wavelengths, visible light, with wavelengths between
`\(0.5 * 10^(-6)\) and \(7 * 10^(-7)\)` meters, is the narrow segment of the spectrum that our eyes can detect. The different colors within visible light correspond to varying wavelengths.

Ultraviolet radiation, X-rays, and gamma rays have progressively shorter wavelengths,
`\(10^(-8)\), \(10^(-10)\), and \(10^(-12)\)` meters, respectively. These high-energy waves are utilized in medical imaging, industrial processes, and sterilization.

Understanding the electromagnetic spectrum is vital as it enables us to harness different regions for diverse applications. The concept highlights the versatility of electromagnetic waves, impacting fields ranging from communication and medicine to astronomy and technology.
