How do we see?

We don’t see objects, but the light reflected from them. When white light hits an object, some of the wavelengths of its constituents. Only a specific wavelength is reflected (any color of the “rainbow”) it is that reflected light that enters our eyes, and then we see some one or an object.

So if anyone asks you what is that? Tell ‘em that’s reflected light

Because of how awesome photons are, I’m going to dedicate an entire blog post to it.
