What is the wavelength and frequency of electromagnetic waves?
The electromagnetic spectrum (EMS) is the general name given to the known range of electromagnetic radiation. Wavelengths increase from approximately 10-18 m to 100 km, and this corresponds to frequencies decreasing from 3 × 1026 Hz to 3 ×103 Hz. The image below shows the names given to different regions of the EMS.
How can you remember the 7 electromagnetic waves?
So from lowest to highest frequency we have radio waves, microwaves, infrared light, visible light, ultraviolet light, x-rays, and gamma rays. Are mneumonic is: Raging Martians Invaded Venus Using X-ray Guns. So you can use that to help you memorize the order of the electromagnetic spectrum.
What is the correct order of the electromagnetic spectrum from shortest wavelength to longest?
Gamma Radiation has the shortest wavelength. Order is as follows (shortest to longest wavelength): Gamma X-Rays UV Visible Infrared Microwaves Radio Waves.
What are the 7 electromagnetic waves and their uses?
The electromagnetic 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) light, X-rays and gamma-rays.
How can I remember my frequency?
Which is the order of the electromagnetic spectrum from lowest to highest frequency?
There are seven regions in the electromagnetic spectrum which in order of lowest to highest frequency are: Radio waves, microwaves, infrared, visible light, ultraviolet, X-rays and gamma rays.
What is the order of the electromagnetic spectrum in order of increasing frequency?
Electromagnetic waves of different frequency are called by different names since they have different sources and effects on matter. In order of increasing frequency and decreasing wavelength these are: radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays and gamma rays.
Which lists the waves in order of frequency from highest to lowest?
In order from highest to lowest energy, the sections of the EM spectrum are named: gamma rays, X-rays, ultraviolet radiation, visible light, infrared radiation, and radio waves.
Which electromagnetic wave has the longest wavelength and lowest frequency?
Radio Waves
Radio Waves — The waves in the electromagnetic spectrum that have the longest wavelengths and lowest frequency are called radio waves.

Which color has highest frequency and shortest wavelength?
The colours vary according to their wavelengths. Violet has the highest frequencies and shortest wavelengths, and red has the lowest frequencies and the longest wavelengths. Encyclopædia Britannica, Inc.
What is the range of the wavelength of the electromagnetic spectrum?
The wavelength range from approximately 200 μm up to a few mm is often referred to as Submillimetre astronomy, reserving far infrared for wavelengths below 200 μm. Mid-infrared, from 30 to 120 THz (10–2.5 μm).
What is the frequency of electromagnetic waves?
Electromagnetic waves are typically described by any of the following three physical properties: the frequency f, wavelength λ, or photon energy E. Frequencies observed in astronomy range from 2.4×10 23 Hz (1 GeV gamma rays) down to the local plasma frequency of the ionized interstellar medium (~1 kHz).
What are the energies and frequencies of the spectrum?
The energies of the spectrum vary from about 3eV on the violet side to 1.5eV on the red side in approximate terms. The frequencies are in the mid 10 14 scales.
What is the Order of electromagnetic waves in the spectrum?
The order of electromagnetic waves in the spectrum is shown in the table below. They are arranged in order of decreasing wavelength (and increasing frequency): Radio waves have the lowest frequencies and longest wavelengths, while gamma waves have the highest frequencies and shortest wavelengths.
