超簡單問題想問..關於wave...

Q: 想問如果一個light wave同一個sound wave 做5做到interference??

A: Of course not. Light wave and sound wave are of different nature. The former is electromagnetic, whereas the latter is mechanical.

Q: 仲有diffraction咪分左3區既?...一區係最光架la...一區就係d 光既diffraction...一區完全冇wave...根據al...邊區為之dark region

A: I suppose you refer to "single slit diffraction".
There is a intensity (i.e. brightness) variation of the light wave after diffracted. The intensity varies from a maximum, decreasing to a minimum (zero intensity), and then rising to a maximum again.

"Dark region" commonly refers to the positions where there are minimum intensity (most commonly, zero intensity).
