@sophiecentaur: Yes, I want a color change but not a significant change. In example I want to change a normal blue to a blue sky. Is it still possible?
@sophiecentaur: I also got some reference said that the frequency will be constant/not change. But the wavelength and the wave speed change from medium to other medium.
@mfb : May be there is a relation to the changing of refraction index from lens (rarer medium)to the microstructure(denser medium) so that it can also change the wavelength of light.
@technician : Yes, I'd like to coat the lens using thin film(microstucture) on its surface, but the lens I used...
In my research, I want to make a transparent lens where there will be a microstructure on its surface.
This lens will be used to change a wavelength of an LED lighting.
Would anyone explain a physics phenomen behind this?
Thank you.
What should I consider if I have three centrifugal pumps then the water of these three pumps flow into one pipe? How to calculate the pressure in the intersection of the three pipes?Thank You.
