Medical students: for treating myopia, image formed by lens is virtual, and for treating hypermetropia the image formed is real, is this correct?

So in the lens formula, if you have to find an image formed by a converging lens, v will be negative, and for diverging lens v will be positive?

Can anyone help me on second part of this question doing turning points don't seem to know how to do it?

For the core unit:

June 2010: What goes on in a nuclear reactor for induced fission
June 2011: How pressure is exerted by gasses
June 2012 Comparison of nuclei radius experiments, electron or alpha scattering
June 2013: Determining a radioactive source
June 2014: Half life of radioactive waste and how it should be stored.

Those are the past 6 markers for anyone who's wondering.

Is my derivation good enough?

Can someone please explain why in June 2014, question 1b(ii) we omit the binding energy of the neutrons from the calculation? Thanks

Yes true, I agree with the eye one - but I don't think we need to know much about how light ray get received by the brain? Also what would you say about endoscope + laparoscopic? I am thinking more of an X-ray question!
