Re: What is Diffraction?

a glass of water with a straw inside is a simple example.
you see the straw bent but it is not.
thats what happen with light when it changes the medium it is travelling
(from air to water or through the glass, example). I am not sure about
what happens with pinhole, once there is no medium change. anyone?
