Color mixing and White light [duplicate]
White light can be produced by the mixing of red, green and blue light.
If one mixes red and green light, one gets yellow.
Why, then, does the mixing of yellow and blue light produce green, rather ...

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" ...

How much red, blue, and green does white light have?
Different kinds of white light have a different spectrum.
Light from a white LED will have blue at the peak intensity while white light from a CFL or something else will have a different looking ...

Why color depends on frequency and not on wavelength? [duplicate]
To explain my question lets consider this example:
The wavelength of light in a medium is $\lambda=\lambda_{0}/\mu$, where $\lambda_{0}$ is the wavelength in vacuum. A beam of red light ($\lambda_{0}=...

How can things around us have different colours if they have specific emission spectra?
Objects appear in different colours because they absorb some colours (wavelengths) and reflect or transmit other colours. The colours we see are the wavelengths that are reflected or transmitted.
As ...

Does a single white photon exist?
Does a photon having superimposed frequencies exist?
(wrt frequency detected by prism or other detectors, not wrt human eye as only rod-cells can detect one photon falling in the detectable (visible) ...

What is the frequency of a photon?
During emission spectrum $$\Delta E=h\nu,$$
where $\nu$ is the frequency.
All books write that it is the frequency of photon, but photon is a particle and not a wave.
More than that what this ...

Is single photon perfectly monochromatic?
Now, we do have equipment to generate single photon at a time, and LASERs are nearly monochromatic.
While typing the question, am realizing that successive photons in case of single photon ...

Why do things have colour? (reflect certain wavelengths of light)
Why does something like an apple, which has many different types of atoms and molecules in different arrangements put together in a complex manner, reflect only certain wavelengths of light, instead ...

What is the distribution of different wavelengths in single ray of white light? Does it remain constant?
Given the sun as the source of light for the above question, does the incident of different visible wavelengths same on a given surface, at a particular time and duration, even if the sun is rotating ...

Kirchhoff's law for glass and transparent crystals; how exactly do hot transparent materials produce so much visible thermal radiation?
Together, the current answers to Is the visible light spectrum from "red-hot glass" at least close to Blackbody Radiation? explain that while we can not necessarily call a heated sample of ...

Confusion about light ray
We represent light by a ray. Again,we know light which is emitted from the sun has all seven colors in them,hence again seven light rays. So doesn't it mean that that light is again composed of $7$ ...
