4:22 shouldn't the new wavefront be slightly curved, not curved all the way back to the obstacle?

Dear sir .When u drew the new plane wavefronts ,u did not draw the ends curve but while passing through a slit ,u drew the ends curved . Why is it so ?I dont understand this point only .😢

Hi. Can this explain why when slit length>wavelength, the diffraction is much smaller (,slit length, the diffraction is much more significant?

Why doesn’t the wavefront at 4:29 carry on around the waves at the top?
@AndyMasley
@AndyMasley 3 жыл бұрын
I imagined there may be more wavefront above it that I didn't include that would cause it to continue in a straight line, but if that's not there it would carry on around the waves. It wasn't the main point of the demo so I ignored it.

You went from a spherical wave to a semi-spherical wave without explanation...

“In all directions” includes the whole circle. A semi center of disturbance. Radiates in all directions except backwards.

@@AndyMasley This is actually a flaw in Huygen's Principle. It ignores, just as you did that if every point is a light source in all directions then it must also go backwards. Nature tells us it doesn't. In 1991 David Miller at Stanford mathematically showed that if every point was a "dipole" rather than a monopole light source then there will be no backward light. This is sort of like Plank solving the Ultraviolet Catastrophe with discrete mathematics but not knowing the why of the discrete nature of Quantum Mechanics. I don't know if his solution stands up in the Physics world that is that photons are dipole. ee.stanford.edu/~dabm/146.html You will probably never draw that semicircle again without considering this. The dipole explanation is a bit daunting but any observant student is bound to say "hey you just drew a circle and said 'every direction'. Does that mean light goes backwards?"

If each point on a wavefront can create another circular wave would we see a single disturbance create multiple waves?

@@AndyMasley usually though a single disturbance only creates one wave so I’m confused on how a wave can create another wave?
