I now understand the Huygens-Fresnel principle but can someone explain how in (at http://en.wikipedia.org/wiki/Huygens%E2%80%93Fresnel_principle) can we ignore the spherical waves and work with only the wavefronts of the created wave source.

Refraction is supposed to take place because there is a difference in the speed of light between the two (or more) media. Why doesn't the light continue in the same direction as before but slower (or faster) ? Thanks, Ishan

Thanks, that video was really helpful. :approve:

I'm sorry if I wasn't clear, I already have a similar understanding of how it turns, my question is how it tends to stay upright when it's traveling in a straight line ( all the other sites say it's because of the gyroscopic effect which has now been proven wrong by...

Hi guys, Why does a Bicycle stay upright ? (It's not because of the gyroscopic forces applied by the wheels as shown by http://ruina.tam.cornell.edu/research/topics/bicycle_mechanics/stablebicycle/StableBicyclev34Revised.pdf) In short this bicycle has wheels of the same size rotating in...
