What exactly is diffraction?

Postby Alice Chang 2H » Sat Oct 12, 2019 12:59 pm

Not sure if someone has already asked this, but I was wondering what diffraction actually is? I looked at the definition which basically defined it as waves that come out of a narrow aperture after a light passes through.
But what is diffraction useful for? Is it measurable and we can use it to find other properties of light?
I'm so lost on this topic LOL

Hey Alice,

I had the same question! I just assumed it was some typeof divergence, but the definition seems to be exclusive to this topic.

Diffraction, in our context, refers to the patterns of high and blow intensities generated by an object in the path of a ray of light. Basically, it is referring to the idea of constructive and destructive interference that shows the wave-like properties of electromagnetic rays.

Hi! I was a bit confused about this topic as well and found this video to be really clear! Hope this helps. https://www.youtube.com/watch?v=1bHipDSHVG4
