Require assistance in physics concepts

  1. Nov 12, 2014 #1
    I didn't know whether to post this here or the homework section. But because this isn't actually homework and there are no questions that require mathematical processes, I thought this would be a better place to post it. Feel free to redirect it to wherever it should belong.

    So quick backstory. I am in high school and am reaching my final exam block. I offhandedly said to the physics teacher that I'd sit his exam, even though I haven't done the subject and having zero prior knowledge. I know this is annoying to help but I am a man(almost) of my word. By the way, due to previous exams for subjects that I actually do, I haven't been able to study this subject until today.

    The exam is in 12 hours and I'd like to be more than a useless duck with a big ego.

    With that being said, these are the concepts I need to learn:

    - Photoelectric Effect, what is it? Honestly, it sounds pretty awesome.

    - Carbon 14 1/2 life and how I could justify it through physics

    - Explaining and understanding fission of nuclei

    - How an electro microscope works

    - Mass defect and Nuclear fission

    I tried looking these up on my own but due to having zero base knowledge on the topic, I don't understand half the terminology.

    well there is a lifetime of study across all those subjects

    sounds like time you learnt how to do research
    have you bothered to google any of them, it would easily provide all your answers ?

    I actually have. However, there are so many terms I don't understand that go hand in hand with these topics that I have no idea how to grasp the concepts.
