Degradation Wave

AI Thread Summary

The wavelength of a 4G data signal transmitted at 700MHz does not change during transit to a smartphone, except for the Doppler shift, which is only significant at high speeds. As the signal travels from the cellphone tower to the device, it maintains its wavelength unless affected by relative motion. For typical scenarios, such as a stationary phone, the Doppler effect is negligible. Therefore, the primary factor affecting the signal remains its original wavelength. Understanding these principles is crucial for grasping wave behavior in telecommunications.

This is probably a simple question, but here is a little background from which to view the problem. A cellphone tower transmits a 4G data signal at 700Mhz to my smartphone. Assuming that it does reach my phone does the wavelength of that databurst change in transit? Thanks.

The only change in wavelength would be as a result of Doppler shift. Unless you are moving very fast, the effect would be neglible.

Thread 'Light speedup question'

If light travels in a wave, couldn't we "speed it up" by making it travel in a straight line?

Thread 'Question about pressure of a liquid'

I am looking at pressure in liquids and I am testing my idea. The vertical tube is 100m, the contraption is filled with water. The vertical tube is very thin(maybe 1mm^2 cross section). The area of the base is ~100m^2. Will he top half be launched in the air if suddenly it cracked?- assuming its light enough. I want to test my idea that if I had a thin long ruber tube that I lifted up, then the pressure at "red lines" will be high and that the $force = pressure * area$ would be massive...

Thread 'Why is the 3 body problem unsolvable? And what will happen if someone solves it?'

I feel it should be solvable we just need to find a perfect pattern, and there will be a general pattern since the forces acting are based on a single function, so..... you can't actually say it is unsolvable right? Cause imaging 3 bodies actually existed somwhere in this universe then nature isn't gonna wait till we predict it! And yea I have checked in many places that tiny changes cause large changes so it becomes chaos........ but still I just can't accept that it is impossible to solve...
