    Sounds right.

    I messed up by saying it applies to all temperatures and collisions need to be elastic.

    Oops

    In my school on the astro ray diagram question, a lot of people did the ray diagram for a refracting telescope in normal adjustment.
    Im pretty sure the question told you to draw the diagram for a magnified real image.

    Oh yeah, and a lot of people wrote virtual in the question before that asking about another feature of the image. i thought it was real

    It was a real image people don't realise the question was talking about just the eyepiece lens not the whole telescope. You was not meant to draw normal adjustment.

    Well multiplied by the radius in order to get the torque so 3*11*cos(45)*0.125

    I did a normal ray diagram with the converging lens being the eyepiece lens, the object between f and 2f and showed that the image formed was inverted, magnified and real. I also showed that the image was past 2f which would work with the values calculated.

    And I wrote that it was real, some people said it said that in the question but it said the OBJECT was real.
