( As a mosquito cannot fly when it is rainy.)ĬONCLUSION1: The radio and light waves are part of the electromagnetic spectrum, but are very different. And that is why they are not able to go through the wall. On the other side, light waves are very very small waves, their size ( wavelength ) is comparable to the size of atoms in the wall. According to the above analogy, that is why they go easily through the wall. I am telling you, radio waves are huge waves, their wavelengths are much much bigger then the size of atoms in the wall. The size of the waves is characterized by their wavelength. You compare the size of the waves and a typical size of atoms in the wall.
#RADIO WAVES ARE LARGER THAN LIGHT WAVES HOW TO#
Now I show you how to use the above example in the case of the waves and the wall. On the other hand, since the size of a boy is much much bigger than the size of a rain drop, it is easy for a boy to run on the street even if it is rainy. If a mosquito entered into the rain, the first few drops would knock the mosquito down to the mud. Why? Because the size of a mosquito is roughly the same as the size of a rain drop. Right? But a mosquito will never fly when it is rainy. The answer to your question is hidden in the comparison of the sizes of the above objects.Ī boy can easily run when it is rainy.
One intuitive and not very precise, but still demonstrating the idea, and a second one, more precise and scientific. Ok, now let us take a look at your question. The differ in their weight.) RADIO waves and LIGHT waves are both PART of the "ELECTROMAGNETIC SPECTRUM", just as say JUDY and JOHN are PART of the "SENIOR CLASS".
It is a name for a bunch of kids going to the same school and being roughly about the same age. ( As an analogy think about "senior class". (Simply speaking, their size.)Ĭheck out our pages of light on the following web page But they also DIFFER in something which is called WAVELENGTH. These waves have in COMMON that they are originated by electric or magnetic processes. Not any kind of waves, ( not acoustic, not mechanical waves) but electromagnetic waves. The words "electromagnetic spectrum" are used to name a group of waves. Let me first make sure the terminology we use is right. If radio & light waves are both properties of the electromagnetic spectrum then why can radio waves pass through walls but light cannot? Why can radio waves pass through a wall but light cannot?
