## What are the 4 types of electromagnetic waves?

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

## What are the 7 types of electromagnetic radiation?

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 is the same for all types of electromagnetic radiation?

Radio, microwaves, UV, visible light and gamma rays have completely different effects, but they’re all exactly the same kind of thing: electromagnetic radiation (EMR). They’re just waves of energy travelling through space — or through things. … Radio waves have got the lowest energy on the electromagnetic spectrum.

## What are 5 examples of electromagnetic radiation?

They include:

• TV waves.
• Light.
• Ultraviolet Light (This is what causes Sunburns)
• X-rays (Just like the kind you get at the doctor’s office)
• Short waves.

## What is the most important electromagnetic wave?

The most important of these is visible light, which enables us to see. Radio waves have the longest wavelengths of all the electromagnetic waves. They range from around a foot long to several miles long.

## How do you detect electromagnetic waves?

To detect the electric fields, use a conducting rod. The fields cause charges (generally electrons) to accelerate back and forth on the rod, creating a potential difference that oscillates at the frequency of the EM wave and with an amplitude proportional to the amplitude of the wave.

## How do you identify radiation type?

To determine the type of radiation (alpha, beta or gamma), first determine the background count rate, then the source count rate with no absorber. Next, place a sheet of paper between the source and the monitor. If the counts are significantly reduced, the source emits alpha particles.

## What types of radiation are not harmful?

Alpha, beta, and gamma rays also cause damage to living matter, in varying degrees. Alpha particles have a very small absorption range, and thus are usually not harmful to life, unless ingested, due to its high ionizing power.

## What are the 2 types of radiation?

There are two kinds of radiation: non-ionizing radiation and ionizing radiation. Non-ionizing radiation has enough energy to move atoms in a molecule around or cause them to vibrate, but not enough to remove electrons from atoms. Examples of this kind of radiation are radio waves, visible light and microwaves.

The different types of radiation are defined by the the amount of energy found in the photons. Radio waves have photons with low energies, microwave photons have a little more energy than radio waves, infrared photons have still more, then visible, ultraviolet, X-rays, and, the most energetic of all, gamma-rays.
