Which of the following waves on the electromagnetic spectrum has the longest wavelength? poi
X-rays
infrared waves
microwaves
gamma rays

Infrared waves have the longest wavelength compared to X-rays, microwaves, and gamma rays. Infrared radiation typically ranges from about 700 nanometers to 1 millimeter in wavelength, making it less energetic but quite useful for applications like remote controls and thermal imaging.

In the real world, infrared waves play a crucial role in technology and nature. For example, they are used in night-vision equipment to detect heat emitted by objects, which is vital in various fields including military, surveillance, and wildlife observation. Plus, plants absorb infrared radiation during photosynthesis, showcasing its importance in sustaining life on Earth!
