# What wavelength does electromagnetic radiation have?

Contents

When EM radiation interacts with single atoms and molecules, its behavior also depends on the amount of energy per quantum (photon) it carries. Spectroscopy can detect a much wider region of the EM spectrum than the visible wavelength range of 400 nm to 700 nm in a vacuum.

## What is the wavelength of an electromagnetic wave?

Electromagnetic waves are categorized according to their frequency f or, equivalently, according to their wavelength λ = c/f. Visible light has a wavelength range from ~400 nm to ~700 nm. Violet light has a wavelength of ~400 nm, and a frequency of ~7.5*1014 Hz.

## 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.

Gamma rays

## How do you find the wavelength of electromagnetic radiation?

To find wavelength ( λ ), the equation is manipulated so that λ=cν . What is the wavelength of a electromagnetic wave that has a frequency of 4.95×1014 Hz ? Once you have frequency, you can use the first equation c=λ⋅ν to find the wavelength.

## What are the 4 main properties of electromagnetic waves?

## What are the 2 types of radiation?

There are two kinds of radiation: non-ionizing radiation and ionizing radiation. Non-ionizing radiation has enough energy to move atoms in a molecule around or cause them to vibrate, but not enough to remove electrons from atoms. Examples of this kind of radiation are radio waves, visible light and microwaves.

## What are the four types of radiation?

There are four major types of radiation: alpha, beta, neutrons, and electromagnetic waves such as gamma rays.

## What are the uses of the 7 electromagnetic waves?

## 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.

## What do all electromagnetic waves have in common?

All electromagnetic waves have two wavefronts, which are an oscillating electric field and an oscillating magnetic field.

## What is the meaning of wavelength?

Definition: Wavelength can be defined as the distance between two successive crests or troughs of a wave. … Wavelength is inversely proportional to frequency. This means the longer the wavelength, lower the frequency. In the same manner, shorter the wavelength, higher will be the frequency.
