What is Inverse square law: Definition and 104 Discussions
In science, an inverse-square law is any scientific law stating that a specified physical quantity is inversely proportional to the square of the distance from the source of that physical quantity. The fundamental cause for this can be understood as geometric dilution corresponding to point-source radiation into three-dimensional space.
Radar energy expands during both the signal transmission and the reflected return, so the inverse square for both paths means that the radar will receive energy according to the inverse fourth power of the range.
To prevent dilution of energy while propagating a signal, certain methods can be used such as a waveguide, which acts like a canal does for water, or how a gun barrel restricts hot gas expansion to one dimension in order to prevent loss of energy transfer to a bullet.
This question came up in my textbook : Describe an example of a force you have experienced that follows the inverse square law. I couldn't think of any that I have "experienced", since I don't think that I have "experienced" the force of gravity that shows it is a inverse relationship.
Inverse square law...intensity-brightness-luminosity-distance
can anyone help me answer this question please
---------------------
recall the inverse square law of intensity of light and use it to relate the brightness of a star to its luminosity and distance from an observer...
Why is it that heat, light, and waves all follow the inverse square law? Why not the inverse cube law? why any law? why doesn't light radiate to 100% of its horizon instead of expanding by mathematical functions?
The best explanation i can come up with is that the inverse square law is a...
