What is the electromagnetic spectrum answer?
The electromagnetic spectrum is a continuum of all electromagnetic waves arranged according to frequency and wavelength. The sun, earth, and other bodies radiate electromagnetic energy of varying wavelengths. Electromagnetic energy passes through space at the speed of light in the form of sinusoidal waves.
Why is it called the electromagnetic spectrum?
“Electromagnetic spectrum” refers to the spectrum of electromagnetic radiation, and electromagnetic radiation is so named because it consists of electric and magnetic fields. In fact, light does affect charges and currents.
What is electromagnetic spectrum Class 11?
Electromagnetic spectrum. Electromagnetic spectrum. When all the electromagnetic radiations are arranged in order of increasing wavelengths, and decreasing frequencies the complete spectrum is called electromagnetic spectrum as shown below: Limitations of this theory.
What are the properties of electromagnetic spectrum?
Electromagnetic waves are typically described by any of the following three physical properties: frequency (f), wavelength (λ), or intensity (I). Light quanta are typically described by frequency (f), wavelength (λ), or photon energy (E). The spectrum can be ordered according to frequency or wavelength.
What is the purpose of the electromagnetic spectrum?
NASA’s scientific instruments use the full range of the electromagnetic spectrum to study the Earth, the solar system, and the universe beyond. When you tune your radio, watch TV, send a text message, or pop popcorn in a microwave oven, you are using electromagnetic energy.
What are some examples of electromagnetic spectrum?
An electromagnetic spectrum is defined as the entire range of electromagnetic waves from low to high frequency. An example of an electromagnetic spectrum is the low frequency radio to the high frequency gamma ray waves.
Which electromagnetic spectrum has the highest energy?
Each section of the electromagnetic (EM) spectrum has characteristic energy levels, wavelengths, and frequencies associated with its photons. Gamma rays have the highest energies, the shortest wavelengths, and the highest frequencies.
What does the electromagnetic spectrum represent?
Electromagnetic Spectrum. Introduction: The electromagnetic spectrum represents the range of wavelengths or frequencies on which that electromagnetic radiation exists. Electromagnetic radiation on this spectrum is important to consider, especially with increasing concerns over Earth and changing climates.
What does the electromagnetic spectrum do?
The electromagnetic spectrum covers a wide range of frequencies from cosmic rays to radio waves. The utility varies widely, for instance, gamma rays are used to destroy tumors, microwaves are used for heating, visible light helps us see, radio waves are used for radio channels.
