| Mar 7 at 15:10 | comment | added | Samj | Alright I just noticed a huge flaw in my answer. The emergent ray must be normal to the emergent wavefront by definition. I will soon correct it. The light indeed does get deflected, exactly like in a prism. A ray shows the general direction of propagation of light, in situations where light interacts with objects much bigger than the order of its wavelength. However, some situations, light seems to defy its ray-like properties (e.g. in interference, diffraction). In such cases, it is better described using waves. The property of phase in waves helps describe these, and explain bending here. | |
