Quick Physics Question:

Can the double slit experiment be performed with radio waves? With gamma rays?

Answer 1

@Astrophysics

Answer 2

I think a possible explanation is the wavelengths. It could be possible to do it with radio waves, as radio waves has wavelengths 100m+.

Answer 3

However, it can't work with gamma rays, as gamma rays have wavelengths of ~1pm or 10^-12 meters. (The size of an atom is 10^-10 meters, so the slit has to be exceedingly small?)

Answer 4

Another explanation for gamma rays could be that gamma rays disrupt ordinary matter, so it would be hard to find a material that can block the rays?

Answer 5

Idk

Answer 6

I'm trying to remember, but from what I recall the wavelength does not matter but rather the angle

Answer 7

the wavelength must be less than the smallest size that you want to realize

for example, to manufacture a transistor on chip at sub micron lengths, the wave length cannot exceed the smallest size that you want to fabricate

Answer 8

and size of slits

Answer 9

so, in our context i think the wavelength must be greater than the slit size for the experiment to be successful

Answer 10

Just to clarify, for the last part you mean smaller right?

Answer 11

It actually works with any wave, what matters here actually is the size of the separation of slits

Answer 12

When i think of slits i think of Youngs Modulus :D. Is that related? Lol

Answer 13

Young's module is double slit :P

Answer 14

If the wavelength is too small, as it is used in fabrication of vlsi chips you get a bright spot... you don't see wave behavior much

Answer 15

well not modulus but yeah youngs experiment xD

Answer 16

There was a set of formulas related to that involving light and dark spots

Answer 17

Hey, I don't remember double slit experiment.... I'm saying that from my knowledge of chip manufacturing

Answer 18

Youngs modulous has to do with elasticity and stoof

Answer 19

I was roughly recalling my knowledge on E&M lol

Answer 20

Young's modulus is a constant which relates stress and strain :

stress = Y*strain

Answer 21

yeah something like that

Answer 22

hey look at this, the equations are of double slit which I think you know but this sums it up

Answer 23

Pretty much lol

Answer 24

Do you really want me to dig out my notes.... haha

Answer 25

I did this like a year ago as well lol so I said lets just check the book now so we don't give wrong info

Answer 26

I feel like it could be valid, but not practical. I think the main issue is the practicality of doing so.

Answer 27

gamma rays is no way practical rofl

Answer 28

Yah

Answer 29

But its possible

Answer 30

any light has both wave and particle behavior
so it must apply to all wavelengths

but if you put the screen right next to the slit, you must shine the slit with a wavelength lesser than the size of slit

Answer 31

Idk what that even means... practicality of this? Its all trial and error young grasshopper :D haha

Answer 32

I gotcha ganeshie

Answer 33

Thanks I think

Answer 34

:p

Answer 35

I'm probably going to ask the professor tomorrow for his perspective though lol x3

Answer 36

I like how it says quick physics question, and 40min later, hehe

Answer 37

Haha it was meant to be a verification ish lol

Answer 38

while you're at studying light, you may like watching this video on chip fabrication

i bet it is completely useless to you... but you might find it interesting :)

Answer 39

Too much time on League eh? What are you, bronze 5? ;p

Answer 40

Ahah Silver 2, but I'm too scared of getting matched with...lets just say questionable teammates... so I don't play ranked too much...

Answer 41

Started recently, so I'm still learning the game :p

Answer 42

https://www.youtube.com/watch?v=DfPeprQ7oGc and watch this on double experiment, it's pretty fascinating talking about electrons through a slit. An interference pattern :O by shooting one at a time? But wait what, how can one electron go through both slits at once this makes no sense..hehe

Answer 43

Gane, I'm always fascinated at how ridiculously precise the machines are
Astro, That was a nice video O.O
