White light is made up of a mixture of different colors. Light travels in waves, and different colors have different wavelengths. Things seem a particular color because of the light they reflect or scatter[散射]—a leaf appears green because it reflects green light. Scattering Light Shine a ...
In this regard, it seems ot me that a wave compressed into a stream, could appear to be a particle stream, but would merely be another wave, with no mass, having properties of both particles and waves, and still not having mass, or speed limit. 3. Then it occurred to me...
Einstein’s theory that the speed of light in vacuum is independent of the motion of the source and the inertial reference frame of the observer has since been consistently confirmed by many experiments. It also sets an upper limit on the speeds at which all massless particles and waves (whic...
He speaks of the new finding:"It’s the sort of thing that’s so obvious; you wonder why you didn’t think of it first." Light travels as particles and as waves. Photons(光子)are the name given to those particles that represent the smallest possible amount of light. At their fastest...
you’d intuitively expect from particles, such as, well, electrons. However, this is not the case. Davisson and Garner showed that when you send electrons through the two slits, they illuminate the screen with not just two, but a long alternate pattern of light and dark bands of...

Light is only a product of our minds. Some "light waves" are invisible (dark) because our minds do not process them. Plants, eggs and sand are completely blind. They see no light whatsoever. Plants photosynthesize energy in the form electromagnetic waves that are completely dark apart from...
The idea that everything is made up of very small particles, or atoms, was known to the Greeks over two thousand years ago, but it was only about one hundred and fifty years ago that John Dalton put forward the important ideas which made the atomic theory really useful and greatly ...
