AI Thread Summary
Materials that selectively transmit red light do exist, such as red cellophane and various optical filters designed for this purpose. The transparency of a material to specific wavelengths depends on its inherent properties. To identify materials that only allow red light to pass through, one can explore optical filters and specialized coatings. These materials can effectively block other wavelengths while permitting red light transmission. Understanding the optical characteristics of these materials is key to finding suitable options.

As you know,the set of light wavelengths that a material is transparent to,is sth dependent on the properties of the material.My question is,can we find a material
which is transparent to a specific wavelength range?
For example,I want a material,which,among the visible light wavelengths,is transparent to only red light.How can I find out what material is that?
Thanks

Red cellophane.
 
There are many optical filters which can do that.
 
Thread 'Question about pressure of a liquid'

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...
