The electro-magnetic spectrum ranges from the very highest frequencies of gamma rays and X-rays through ultra-violet, visible light, infra-red and radio waves.
Fortunately for us, much of the ultra-violet light from the sun is blocked by the atmosphere as are X-rays and gamma rays. Although some can penetrate the atmosphere, the intensity is much reduced. This feature of the atmosphere stops us being damaged by potentially harmful energy.
Visible light and infra-red can both reach the earth through the atmosphere - the fact that the sun lights up the earth demonstrates this very well.
Radio waves are also able to pass through the atmosphere with relative ease. Terrestrial radio and television broadcasts can be carried for long distances and of course, satellite communication shows that radio signals can pass up and down through the atmosphere.
Be aware that propagation of electro-magnetic waves is a complex science and this answer is only the briefest of overviews.
What else can I help you with?
What velocity do all parts of the em spectrum travel at?
All parts of the electromagnetic spectrum travel at the speed of light in a vacuum, which is approximately 299,792 kilometers per second. This speed is a fundamental constant of nature and does not change regardless of the type or frequency of electromagnetic radiation.
What characteristics do all parts of the electromagnetic spectrum share?
All parts of the electromagnetic spectrum travel at the speed of light in a vacuum, have both electric and magnetic properties, and can exhibit wave-particle duality. Additionally, they all have the ability to interact with matter, such as being absorbed, reflected, or transmitted.
What is different about the different parts of the electromagnetic spectrum?
The electromagnetic spectrum consists of different wavelengths of electromagnetic radiation, ranging from radio waves to gamma rays. Each part of the spectrum has unique properties, such as frequency, energy, and interaction with matter. Different parts of the spectrum are used for various purposes, from communication (radio waves) to medical imaging (X-rays).
Why can you see some of the spectrum and not all of it?
Humans can see a limited portion of the electromagnetic spectrum called visible light, which ranges from red to violet. Our eyes have evolved to detect these wavelengths, as they are most relevant for our survival. Other parts of the electromagnetic spectrum, such as infrared and ultraviolet, are invisible to us because our eyes lack the receptors to detect them.
Why do different parts of the electromagnetic spectrum have different properties?
Different parts of the electromagnetic spectrum have different properties because they have different wavelengths and frequencies. These differences affect how they interact with matter and how they are detected by instruments. For example, shorter wavelengths like X-rays are more penetrating, while longer wavelengths like radio waves can travel farther through obstacles.
What are the parts of electromagnetic spectrum?
radio waves
Which best explains the relationship the electromagnetic spectrum and sight?
Visible light and infrared light are the parts of the electromagnetic spectrum that can be seen with the eye.
Which best explains the relationship between the electromagnetic spectrum and sight?
Visible light and infrared light are the parts of the electromagnetic spectrum that can be seen with the eye.
In some parts of the electromagnetic spectrum the atmosphere is described as opaque What does this mean for remote sensing?
When the atmosphere is opaque in certain parts of the electromagnetic spectrum, it means that the radiation in those wavelengths is largely absorbed or scattered by the atmosphere. This can limit the ability of remote sensing instruments to gather data in those specific wavelengths, affecting the accuracy and quality of the observations. Scientists need to consider these atmospheric effects when interpreting remote sensing data to ensure reliable results.
Is the visible spectrum dangerous?
No, it is not dangerous. It is just the colors that are absorbed by the light. Some parts of the electromagnetic spectrum are dangerous, however. To learn more in depth and to get more of an explanation on the visible spectrum and the electromagnetic spectrum, visit wikipedia.
What parts of the electromagnetic spectrum are ionising?
X-rays and gamma rays are the parts of the electromagnetic spectrum that are ionizing, meaning they have enough energy to remove electrons from atoms or molecules.UV light can also be ionizing, but to a lesser extent.
Why are some parts of the electromagnetic spectrum called light and others called waves?
No reason. Light is an electromagnetic wave so you can call any part of the spectrum either.
What three parts of the electromagnetic spectrum contains the majority of the sun's rays?
yellow
How are x-rays and gamma rays related?
Both are the parts of electromagnetic spectrum.
What are Not visible parts of the electromagnetic spectrum?
You can't see the different colors that are shown
What are the direct and indirect effects of the electromagnetic spectrum on the life of earth?
The direct effects of the electromagnetic spectrum on Earth include providing sunlight for photosynthesis and warmth for sustaining life. Indirect effects include the impact of electromagnetic radiation on climate change due to the absorption and reflection of sunlight by the Earth's surface and atmosphere. Additionally, exposure to certain parts of the spectrum, such as ultraviolet radiation, can have harmful effects on living organisms, including human health.
What velocity do all parts of the em spectrum travel at?
All parts of the electromagnetic spectrum travel at the speed of light in a vacuum, which is approximately 299,792 kilometers per second. This speed is a fundamental constant of nature and does not change regardless of the type or frequency of electromagnetic radiation.
