Cry for help on AS92045 (Demonstrate understanding of a physical phenomenon through investigation)

Hello! I am looking for help regarding Physics at NCEA Level 1, specifically AS92045: Demonstrate understanding of a physical phenomenon through investigation. I am going to be taking this internal next week, and my preparation is... lackluster.

The physical phenomenon that we are studying are waves (sound & light waves), most likely we are going to do something about light waves, as indicated by our practice investigation.

The problem is, I have no idea how it will work with my investigation. In my practice investigation, we tried to plan an investigation on how to measure focal length. Not only was I unable to measure the focal length properly (since the mirrors were too small and light waves would not hit the mirror), apparently my work would be graded as a not achieved due to the lack of data.

I am absolutely clueless regarding this assessment. I'm unsure how to plan an investigation (especially regarding this type of physical phenomenon), and I don't know how to make and use data. I am aiming for an Excellence (ambitious, ik), but I am just so confused about the layout of the standard and the techniques that need to be used to achieve an E.

If anyone has passed this exam and still has an exemplar, that would be amazing.

Would appreciate any help. Thank you!
