- a problem with an information i read.
I read in a book that high frequency electromagnetic waves are more able to penetrate than low ones , so why radio waves can penetrate walls when light cannot?
I think it is true if photons rather than EM waves are considered. E = h⋅u ;samy4408 said:I read in a book that high frequency electromagnetic waves are more able to penetrate than low ones , so why radio waves can penetrate walls when light cannot?
The higher the frequency of an electromagnetic wave, the lower its ability to penetrate materials. This is because higher frequency waves have shorter wavelengths, making it easier for them to be absorbed or reflected by objects in their path.
Higher frequency waves have more energy, which means they can interact more strongly with atoms and molecules in materials. This leads to more absorption and reflection, reducing the wave's ability to penetrate through objects.
The penetration of electromagnetic waves can determine the effectiveness of certain technologies. For example, high frequency waves are used in medical imaging because they can penetrate through soft tissues, while low frequency waves are used in communication technologies because they can travel long distances through the atmosphere.
Yes, high frequency waves can still penetrate through some materials, especially those with low density or thin layers. However, their ability to penetrate decreases as the frequency increases.
Understanding this relationship is important in various fields, such as engineering, medicine, and telecommunications. It allows us to design and use technologies that utilize the appropriate frequency for their intended purpose, and also helps in understanding how electromagnetic waves interact with different materials.
