Ian Martin Posted May 21, 2019 Share Posted May 21, 2019 Im just an ordinary guy with a question, dont know mych about physics.. here is my question.. How do we know that light travels in waves compared to a forward circular motion? Link to comment Share on other sites More sharing options...
swansont Posted May 21, 2019 Share Posted May 21, 2019 It undergoes interference and diffraction, which are wave behaviors Link to comment Share on other sites More sharing options...

How do we know that light travels in waves compared to a forward circular motion? What is a "forward circular motion"? Do you mean rolling along like a wheel? Or maybe like a corkscrew?

MigL Posted May 24, 2019 Share Posted May 24, 2019 I assumed he meant 'radial'. emanating from a central point outward. Maybe not. Link to comment Share on other sites More sharing options...
AUDI R6 Posted July 15, 2019 Share Posted July 15, 2019 Light is an electromagnetic wave , which can be seen by the bending of the polarisation of the light when it passes through a magnetic field . But light is absorbed / emmited in photons which are particles with quantisized energy(factor of a constant).This is called quanta . So light has a dual nature , it is not a wave , not a particle but both wave and particle . Link to comment Share on other sites More sharing options...
