## What does the electromagnetic scale measure?

Electromagnetic radiation can be expressed in terms of energy, wavelength, or frequency. Frequency is measured in cycles per second, or Hertz. Wavelength is measured in meters. Energy is measured in electron volts.

## What is the scale of electromagnetic radiation?

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.

Type of Radiation Frequency Range (Hz) Wavelength Range
microwaves 3*1011 – 1013 1 mm – 25 μm
radio waves 11 > 1 mm

## What are the 7 different radiations on the electromagnetic scale?

The electromagnetic spectrum includes, from longest wavelength to shortest: radio waves, microwaves, infrared, optical, ultraviolet, X-rays, and gamma-rays.

## What is the electromagnetic spectrum simple definition?

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 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.

## What is the highest frequency color?

When it comes to visible light, the highest frequency color, which is violet, also has the most energy. The lowest frequency of visible light, which is red, has the least energy.

Despite extensive research, to date there is no evidence to conclude that exposure to low level electromagnetic fields is harmful to human health. The focus of international research is the investigation of possible links between cancer and electromagnetic fields, at power line and radiofrequencies.

## What is the highest energy?
