# What is the longest region of the electromagnetic spectrum?

Contents

Radio waves have the longest wavelength, and gamma rays have the shortest wavelength.

Gamma rays

## What are the 7 electromagnetic waves in order smallest to largest?

The electromagnetic spectrum includes, from longest wavelength to shortest: radio waves, microwaves, infrared, optical, ultraviolet, X-rays, and gamma-rays.

## Is the electromagnetic spectrum infinite?

In general the frequency spectrum for Electromagnetic (e.g light, radio, etc) is continuous and thus between any two frequencies there are an uncountable infinity of possible frequencies (just as there are an uncountable number of numbers between 1 and 2).

## What are the 7 types of electromagnetic radiation?

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.

## 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 highest frequency?

Audio frequencies are expressed in hertz (Hz); although experts don’t always agree on specific values, the overall consensus is that high-frequency sounds start at 2,048 Hz. Moving backward, the range between the lowest treble and 256 Hz is known as midrange audio.

Gamma rays

## What types of waves exist?

Waves come in two kinds, longitudinal and transverse. Transverse waves are like those on water, with the surface going up and down, and longitudinal waves are like of those of sound, consisting of alternating compressions and rarefactions in a medium.

## What spectrum means?

A spectrum (plural spectra or spectrums) is a condition that is not limited to a specific set of values but can vary, without steps, across a continuum. The word was first used scientifically in optics to describe the rainbow of colors in visible light after passing through a prism.

## Who discovered the electromagnetic spectrum?

James Clerk Maxwell

## Where is WIFI on the electromagnetic spectrum?

Wifi occupies the radio frequency band of the electromagnetic spectrum between actual radio waves and microwaves (used to listen to the game, and cook your dinner, respectively).
