Your question: What is spectrum of electromagnetic wave?

What is electromagnetic spectrum explain?

electromagnetic spectrum, the entire distribution of electromagnetic radiation according to frequency or wavelength. … The electromagnetic spectrum comprises the span of all electromagnetic radiation and consists of many subranges, commonly referred to as portions, such as visible light or ultraviolet radiation.

What type of spectrum do electromagnetic waves form?

Electromagnetic waves form a continuous spectrum of waves. This includes: waves with a very short wavelength , high frequency and high energy. waves with a very long wavelength, low frequency and low energy.

What is the spectrum of wavelength?

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.

The EM spectrum.

Type of Radiation Frequency Range (Hz) Wavelength Range
visible 4 – 7.5*1014 750 nm – 400 nm
near-infrared 1*1014 – 4*1014 2.5 μm – 750 nm

What is the electromagnetic spectrum order?

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.

What is electromagnetic spectrum Slideshare?

The electromagnetic waves are grouped into types that have similar wavelengths and so have similar properties. Electromagnetic waves form a continuous series in order of changing wavelength, frequency and energy. This series is called the electromagnetic spectrum.

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 characteristics of electromagnetic spectrum?

The characteristics of the electromagnetic spectrum are the propagation features and the amount of information, which signals can carry. In general, signals sent using the higher frequencies have shorter propagation distances but a higher data-carrying capacity.

Is the electromagnetic spectrum transverse or longitudinal?

Electromagnetic waves are transverse waves. That means the electric and magnetic fields change (oscillate) in a plane that is perpendicular to the direction of propagation of the wave.

What is beyond the electromagnetic spectrum?

These represent the outer limits of the light that we can see, but the electromagnetic spectrum continues far beyond these narrow confines. At wavelengths slightly longer than red, we get infrared radiation, and beyond that we get terahertz radiation and then microwaves.

Is the electromagnetic spectrum infinite?

The full set of EM radiation is called the electromagnetic spectrum. To simplify things the EM spectrum divided into sections (such as radio, microwave, infrared, visible, ultraviolet, X-rays and gamma-rays). The EM spectrum is continuous (has no gaps) and infinite.

When was the electromagnetic spectrum discovered?

In 1887 Heinrich Hertz demonstrated the existence of the waves predicted by Maxwell by producing radio waves in his laboratory. It took a bit longer for scientists to discover the higher-energy (shorter wavelength) light in the electromagnetic spectrum.

What is meant by electromagnetic spectrum give its four uses?

The electromagnetic spectrum is a continuum of all electromagnetic waves arranged according to Waves and Frequency. EM spectrum uses are: Communication, treat cancer, sterilize medical equipment, killing living organisms.

What is the highest frequency?

Gamma rays have the highest frequency in the electromagnetic spectrum. They have a frequency of the order of about 1020 to 1022 Hz.
