3.9 understand that waves can be diffracted through gaps, and that the extent of diffraction depends on the wavelength and the physical dimension of the gap.
Diffraction can happen through a gap, when waves go through a narrow space, on continuing they spread out again. The smaller the gap, in comparison to the wave length, the larger the diffraction.

Do we need to know why this happens or just that it does for an AQA IGCSE?
ReplyDeleteIt's fairly logical if you think of it like someone pushing a flexi ruler or an object like that through a gap which is too small for it to fit through by itself the ruler will bend to get through the gap the smaller the gap the more it has to be bent to fit through and the same with waves only once the wave has been diffracted it stays that shape until it reaches another object
ReplyDeleteThats actually a great example
