Sep 18, 2012 · Our eyes detect the light and send electrochemical impulses to our brains visual cortex. Here our brain interpretation these impulses and creates a visual representation of the object, from which the light originates. We then perceive the representation. "This is the part which most people struggle to comprehend."

Aug 10, 2016 · All electromagnetic radiation is light, but we can only see a small portion of this radiation—the portion we call visible light. Cone-shaped cells in our eyes act as receivers tuned to the wavelengths in this narrow band of the spectrum. Other portions of the spectrum have wavelengths too large or too small and energetic for the biological ...

These different colours of light have different wavelengths and frequencies. Red light has the longest wavelength, and the lowest frequency of the visible spectrum. Violet has the shortest wavelength, and the highest frequency of the visible spectrum.
Mixing coloured materials, such as paint, is an example of subtractive colour mixing. Red paint appears red to us because when white light strikes it, the red pigments reflect the red wavelengths of light and absorball of the wavelengths. This reflected light is what is seen by our eyes. The same is true for all of the other colours. So what about ...
Light travels very fast - at the speed of light in fact!Light travels as waves.Light travels in straight lines.Despite the apparent oxymoron, we humans can’t see light. We can only see objects that are illuminated by light, not the light itself. The light-sensitive components of our eyes – the so-called rods and cones that respond favourably to a tiny range of radiation within the much broader electromagnetic spectrum – don’t see the radiation at all, despite what it says on the box.
Jul 29, 2015 · Here, we can also see that some of the light reaching those points on the ground is reflected back to the observer, confirming the inference. The observer, illustrated as an eye, is a light detector which only detects light reaching it, the observer, not light which doesn't reach it. (That's the short answer to the question.)
Dec 15, 2021 · The more energy an electron has, the farther it is from the nucleus. Atoms make light in a three-step process: They start off in their stable "ground state" with electrons in their normal places. When they absorb energy, one or more electrons are kicked out farther from the nucleus into higher energy levels.

Why can't we see photons but can see objects?
The simple answer is NO! We only see the effect of light that happens in our eyes. The light cause a chemical reaction in light-sensitive cells of our eyes. These reactions produce electrical signals that are transferred to the brain by the optic nerve. Moreover, light is the small portion of the electromagnetic spectrum that our eye can detect.
