Electron wavelength vs. light(s) wavelengths
I am doing some research into wave and waveform. I am looking at different types of microscopy for potential purchase. However, I came across Max Knoll a minute ago and I am curious as to how ...

Upper limit of energy carried by one photon [duplicate]
energy carried by one photon, $E = hυ$ where $υ$ is frequency and $h =$ planck constant. Is there any upper limit to how much energy one photon can carry? or any upper limit of frequency?

Is the redshift/distance relationship of light 100% correlated to an expanding universe?
We know that the light we measure from distant galaxies is red-shifted; the red-shift is proportional to distance; we attribute this to the expansion of space at the rate of the Hubble constant/...

Why is everything not invisible if 99% space is empty?
If every object is $99$% empty space, how is reflection possible? Why doesn't light just pass through?
Also light passes as a straight line, doesn't it? The wave nature doesn't say anything about its ...

Zero-dispersion wavelength
Please help me understanding the zero-dispersion wavelength in fibers.
I found this wiki-article on the topic. Accordingly:
"In a single-mode optical fiber, the zero-dispersion wavelength is the ...

Is there a finite number of colors in the visible spectrum? [duplicate]
Does quantum theory and Planck's length of $1.6\times10^{-35}\ \mathrm{m}$ mean that the electromagnetic spectrum is not continuous as every photon can only carry a discrete amount of energy?
If so, ...

Does reflection depend on wavelength?
I'm aware of processes like Rayleigh scattering, Compton scattering and pair production. But as these processes treat light as being particles(?) I'm not sure whether they are helpful to understand ...

Why does the maximum of Planck's distribution function depend on how it is plotted? [duplicate]
I was reading Fundamentals of Atmospheric Radiation by Craig F. Bohren and Eugene E. Clothiaux and in page 20-23 they discuss the idea that the maximum of the Planck's distribution varies depending on ...

Do the "colors" live in a 3-dimensional vector space? [closed]
Do the "colors" form a 3-dimensional vector space?
Colors are just different frequencies of electromagnetic lights, from the low frequency (infra-red, red) to the high frequency (blue, ...

Wavelength of light in a waveguide
I've done a derivation showing that the wave length of light in a waveguide is longer than that of free space light. But I don't really have an intuitive understanding of why this is. I think my prof ...

Does $f = (c + v) /$wavelength?
If I'm heading at some given velocity into an electromagnetic wave with some given wavelength.
From my POV it would appear as if the wave has sped up towards me and as a consequence the wavelength of ...

What does the "true" visible light spectrum look like? [closed]
When I google "visible light spectrum", I get essentially the same image. However, in each of them the "width" of any given color is different.
What does the "true" ...

Does a single photon have a wavelength or not? [duplicate]
I have read this question where anna v says:
The photon is an elementary particle in the standard model of particle physics. It does not have a wavelength.
What exactly is meant by the wavelength of ...

Is it possible to confine a photon in less than its* wavelength?
*(Its, or associated. That is somehow the question).
I can think of, at least in principle, a perfectly reflecting optical cavity with dimension comparable to the wavelength of the electromagnetic ...
