Yes, for definitions. You need to leave your cheat sheet with your exam though don't you? So they'd know if you copied an answer word for word?
laseredd, at the TSFX lectures they said it is valid to explain how the particle model does not explain Young's experiment as a point in your answer.
You don't hand in your cheat sheet at the end of the exam.
My irrelevant point was that it would be a valid way

. I looked back, it wasn't VCAA 2010. I can't remember which question I'm thinking of.
Either way it was just an example about how much detail you need to go in, if you treat it as a fictional question (one that deals asks only for the wave model) providing that extra discussion would be unnecessary and not score you any extra marks.
Back to that that VCAA question, that is a good (and correct) example of the level detail you need to provide. I provided this pretty detailed answer that explained what both of the models predicted. Then I looked at the assessor's and it was like two sentences:
"Young’s double slit experiment demonstrated interference, which was a wave effect. The particle model predicted that
two bands would appear on the screen behind the slits."
That was all that was required to sufficiently answer the question. Anything else was irrelevant and would not contribute to extra marks.
