?Radio Waves vs Visible Light: Is it Correct?

In summary, longer wavelengths generally penetrate deeper through material than shorter wavelengths, but it is not always true as it depends on factors such as the properties of the material and the type of waves being used. Further understanding of the nature of light and matter is needed to fully explain this phenomenon.

Longer wave lengths always penetrate deeper than shorter wavelengths.

OTOH, they also carry less energy.

That is not always true. X-rays penetrate deeper through matter than visible light, yet are of a shorter wavelength.

Electromagnetic propagation is a complex subject, especially when talking about a medium with multiple layers of differing properties such as the atmosphere. There are few simple rules.

It doesn't answer your question exactly, but if you'd like some info regarding radio wave transmission check out module 10, chapters 1 & 2 here: http://www.navymars.org/national/training/nmo_courses/NMO1/NMO1.htm

There is no simple explanation and in fact is note entirely true. The ionosphere blocks long radio waves effectively. To understand how some particular wavelength interacts with some particular material requires a deep understanding of the nature of light, matter, and their interactions. You might as well have asked the simpler question "Why is glass transparent" and you've gotten pretty much the same answer.
 

FAQ: ?Radio Waves vs Visible Light: Is it Correct?

What are radio waves and visible light?

Radio waves and visible light are both forms of electromagnetic radiation, which are energy waves that travel through space. They differ in terms of their wavelengths and frequencies, which determine the type of energy they carry.

How do radio waves and visible light differ?

Radio waves have longer wavelengths and lower frequencies compared to visible light. This means that they have lower energy and cannot be detected by the human eye. Visible light, on the other hand, has shorter wavelengths and higher frequencies, which allows us to see it.

Can radio waves and visible light be used for the same purposes?

Yes, both radio waves and visible light can be used for communication and transmission of information. However, they are used in different ways and have different applications. Radio waves are commonly used for long-distance communication, while visible light is used for short-range communication.

Is it correct that radio waves and visible light behave differently in certain environments?

Yes, radio waves and visible light can behave differently when they pass through certain materials or environments. For example, visible light can be refracted or absorbed by objects, while radio waves can pass through them. This is why different types of electromagnetic radiation are used for different purposes.

How are radio waves and visible light used in everyday life?

Radio waves are used in many technologies, such as radios, televisions, and cell phones. They are also used for navigation systems, such as GPS. Visible light is used for lighting and vision, as well as in technologies like fiber optics for high-speed internet. Both forms of radiation are essential for our daily lives and have many practical applications.
