Why don鈥檛 buildings block radio waves as completely as they do visible light?

Short Answer

Expert verified

The buildings block radio waves as completely as they do visible light due to the smaller size of the wall.

Step by step solution

01

Definition of Wavelength

The distance between any point on a wave's advance line and the next point of the same phase. A specific path or stream of thinking, particularly as it relates to mutual understanding between two persons who are on different wavelengths.

02

Explain buildings block radio waves as completely as they do visible light

If the object's size is larger than the wavelength of the electromagnetic radiation, the object is the only one who can notice the wave. However, if the object's size is smaller than the wave's, the object will be unable to detect the wave.

The wavelength of the wave is the size of the wave in this case. As a result, the size of a radio wave is significantly larger than the size of a building wall. As a result, constructing a wall will not be able to entirely stop it. The size of visible light, on the other hand, is significantly smaller than the size of the wall. As a result, erecting a wall will fully obstruct it.
