Quick Answer: What Is The Electromagnetic Spectrum Used For?

What are the 7 electromagnetic waves and their uses?

The EM spectrum is generally divided into seven regions, in order of decreasing wavelength and increasing energy and frequency.

The common designations are: radio waves, microwaves, infrared (IR), visible light, ultraviolet (UV), X-rays and gamma rays..

Why do scientists use the electromagnetic spectrum?

By studying the electromagnetic waves given off by objects such as stars, galaxies, and black holes, astronomers can better understand the universe. Telescopes are designed to detect a specific portion of the electromagnetic spectrum.

What is the electromagnetic spectrum simple definition?

The Electromagnetic Spectrum. The electromagnetic (EM) spectrum is the range of all types of EM radiation. Radiation is energy that travels and spreads out as it goes – the visible light that comes from a lamp in your house and the radio waves that come from a radio station are two types of electromagnetic radiation.

What is the most important electromagnetic spectrum?

The most important of these is visible light, which enables us to see. Radio waves have the longest wavelengths of all the electromagnetic waves.

What is the most important part of the electromagnetic spectrum?

Even as these organisms moved to land, visible light still proved to be the most useful part of the electromagnetic spectrum to see—radio waves would make it difficult to resolve small objects, X-rays tend to like to pass through matter, and UV rays can damage both our skin and our eyes.
