De Broglie wavelenght of Earth and Moon

Click For Summary

Discussion Overview

The discussion revolves around calculating the de Broglie wavelength, frequency, and energy of the Earth and Moon based on their respective velocities and masses. The context includes theoretical physics and applications related to sound frequencies derived from these calculations.

Discussion Character

  • Technical explanation
  • Debate/contested
  • Exploratory

Main Points Raised

  • One participant requests calculations for the de Broglie wavelength, frequency, and energy of the Earth at various velocities and for the Moon, providing relevant formulas and constants.
  • Another participant suggests using online tools to perform the calculations independently.
  • A participant expresses frustration at the lack of assistance and clarifies that they are not seeking homework help but rather support for a creative project involving sound.
  • One participant provides a calculated de Broglie wavelength for the Earth, suggesting it is approximately 3E-54 meters, and discusses the corresponding frequency in a humorous context.
  • There is a discussion about whether the Moon can have multiple wavelengths relative to different frames of reference, with a participant seeking clarification on this point.
  • Another participant suggests scaling the frequencies to fit within the audio range for the project.
  • Several participants engage in light-hearted banter regarding hearing ranges and age-related differences in frequency perception.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the calculations, and there are multiple competing views regarding the interpretation of the de Broglie wavelength and its implications for the Earth and Moon. The discussion remains unresolved with respect to the specific values needed for the project.

Contextual Notes

Some participants express uncertainty about the calculations and the applicability of the de Broglie wavelength in the context of sound. There are also limitations in the understanding of how to derive the necessary values for the creative project.

Who May Find This Useful

This discussion may be of interest to individuals exploring the intersection of physics and music, particularly those looking to understand the implications of quantum mechanics on sound frequencies.

Hi,

Could someone please crunch for me the de Broglie wavelength (\lambda), frequency (f) and energy (E) of Earth at perihelion (30300m/s) and at aphelion (29300m/s) and mean (29800m/s)

Here are the numbers and formulas:

\lambda=h/p , f=E/h , p=m*v (momentum=mass*velocity)

h - Planck's constant = 6.62606896×10-34
p -
m - 5.9742×1024kg
v1 - 30300m/s
v2 - 29300m/s

And also for the Moon:

m - 7.347×1022kg
v - 1022 m/s (mean v around the Earth)
v - 29783 m/s (mean v around the Sun)

What would be the wavelength/velocity of an object going around two centers? Thanks,

Plug in your values for the equation there, with the proper units and get the answer yourself :)
 
come on people I need those numbers...

I don't understand what you mean, you already have the numbers and you just need to plug them in the given equations.I hope you're not asking people here to do the calculations for you,some may be willing to check your work but you must show your own efforts first.If you have difficulty in understanding the question and what to do then come back.
 
dadface,
Yes, I need someone to do the calculations for me. This is not a homework or some exercise. I'm a musician and I'm working on a track that uses frequencies derived or modulated from the physical properties of Earth and Moon but my math skills drop dead beyond addition and subtraction.
So, yea this is probably the first time in the history of physics where wavelength of Earth and Moon is really really really needed :)
It might seem easy to you but I've never done this sort of math before so I thought I should look for help from people involved with physics and math. I guess this is not the right place.

Can you direct me to a place where I can get help with this?

Thanks,
 
Well, the de Broglie wavelength of the Earth (relative the Sun's frame of reference) is about 3E-54 meters, which, if it were turned to sound, would be a frequency of about 1E56 Hz.

About a hundred-septillion-septillion megahertz.

Personally I can't hear that well above 18 kHz.

This sounds like an interesting project olovomax.Perhaps you could scale the frequencies down so they come within the audio range.Good luck with it.

You must be a young person.I'm an old geezer and I'm guessing that about 12kHz is my upper range.:biggrin:

Sweet!

So the Earth is buzzing at 10e55 Hz. Is that correct?
What about the moon, alxm? Can the moon have two wavelengths as relative to the Earth and the sun or it's a mean value? I think I can set the frame of the track on the ratio of three values - either of earth-moon-sun or earth-moon(Earth)-moon(Sun)

I need only 3 values to lay the grid for this track.

thanks i'll let you hear it when I'm done with it

if your upper limit was at 12kh you would be half deaf :D

the 10-16kh range is reserved mainly for predation - therefore if you lived as a hunter-gatherer in you would probably starve to death too :)
