Can anyone explain the difference between progressive waves and stationary waves? Progressive waves make up a stationary wave, is it?
The way I think of it is a progressive wave appears to move horizontally, whereas a stationary wave just oscillates in the same position.
But yes... A stationary wave if formed when two progressive waves of the same amplitude and frequency, in the same mediumm, travelling in opposite directions superpose to produce points of zero displacement (nodes) and maximun displace (antinodes).
Can someone explain the diffraction grating pattern with white light, Im like
diffraction grating with white light produces fringes that have colours of the spectrum. the zero order is just white light since all the wavelengths pass through it. and the 1st and 2nd and more orders have the spectrum, roygbiv on one side and mirrored on the other side so vibgyor.
I used to Like physics, got an A in the first unit, but I CANT DO THIS SH*T haha
Dude I'm with you on that. I love physics, but these waves and optics chapters make me want to throw up, seriously. Unit 1 is so much easier (which btw, I havent took yet - also taking that that in may, in 5 days )

dont actually know a single thing about moments or mechaics -.- god im screwed for unit 2! and does anyone have any advicce on the long answer questions i usualy leavethem not having a clue what to do
I'm scared of the weird word questions they can throw up (especially 6 markers). I understand the physics, but I am unsure what to put to get the marks... (and I often don't ).
