What are the 7 types of waves in the electromagnetic spectrum PDF?

This range is known as the electromagnetic spectrum. 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 are the 7 colors of the electromagnetic spectrum?

Visible Light Spectrum Visible light travels at a speed of 300,000 km per second and can be broken down into seven colors. From longest to shortest wavelength, they are: red, orange, yellow, green, blue, indigo, and violet. To be clear, color is the eye’s perception of different wavelengths of electromagnetic light.

How are EM waves arranged in the spectrum?

The electromagnetic spectrum is a continuum of all electromagnetic waves arranged according to frequency and wavelength. The shortest waves are gamma rays, which have wavelengths of 10e-6 microns or less. The longest waves are radio waves, which have wavelengths of many kilometers.

What EM waves are the strongest?

The Electromagnetic spectrum lists the most powerful EMR, gamma rays, to the least powerful EMR, radio waves. In addition, the highest energy waves (gamma, x-ray) have the shortest wavelengths. The lowest energy waves, radio waves, have longest wavelengths.

Which EM waves has the longest wavelength?

Radio Waves — The waves in the electromagnetic spectrum that have the longest wavelengths and lowest frequency are called radio waves. Radio waves are used to transmit information from the antenna of a broadcasting station to the antenna of your radio or TV.

What are the 7 types of electromagnetic waves in order?

Arranged in terms of decreasing wavelengths, these 7 types of electromagnetic waves are Radio waves, Microwaves, Infrared light, Visible light, Ultraviolet light, X-rays, and Gamma-rays. As the wavelength reduces, the energy of the emitted wave increases.

What is the wavelength of electromagnetic waves in the EM spectrum?

The EM spectrum. 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*10 14 Hz.

What is electromagnetic spectrum according to Luc braybury?

By Luc Braybury. The electromagnetic (EM) spectrum encompasses all wave frequencies, including radio, visible light and X-rays. All EM waves are made up of photons that travel through space until they interact with matter; some waves are absorbed and others are reflected.

What type of electromagnetic waves are used in microwave ovens?

Electromagnetic waves with shorter wavelengths and higher frequencies include ultraviolet light, X-rays, and gamma rays. Electromagnetic waves with longer wavelengths and lower frequencies include infrared light, microwaves, and radio and television waves. Two microwave frequencies are authorized for use in microwave ovens, 900 and 2560 MHz.
