The electromagnetic spectrum refers to the range of all possible wavelengths of electromagnetic radiation, which includes radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays.
Imagine the electromagnetic spectrum as a buffet table with different types of food. Each type of food represents a different wavelength range. Just like how you can choose from a variety of dishes at a buffet table depending on your preference, scientists can study different types of electromagnetic waves depending on their wavelength.
Radio Waves: These are the longest wavelengths in the electromagnetic spectrum and are used for long-distance communication.
Visible Light: This is the part of the spectrum that humans can see and is responsible for our sense of vision.
Gamma Rays: These are extremely high-energy waves with the shortest wavelengths in the spectrum. They are often produced during nuclear reactions.
