    Do we need to know how the actual microscopes work like the whole procedure of how image is obtained for aqa?

    • @MrPollockBiology
      @MrPollockBiology  9 лет назад

      Useful to know that Transmission involves electrons passing through sample, Scanning involves reflected electrons.
      Most commonly, examiners will ask for differences between light and one other EM, or will ask which microscope was used to make a given image, and why.

    • @AlchemistOfNirnroot
      @AlchemistOfNirnroot 9 лет назад

      Mr Pollock I'm here for the physics. I doubt you need to know about electron's having wavelength (λ=h/p) which can be easily derived.

    Also 5:50 dont u mean how many electrons are reflected?

    • @MrPollockBiology
      @MrPollockBiology  9 лет назад

      The false colour works because the sample is stained with heavy metals, which change how many electrons are absorbed in certain regions.
      This works in both TEM and SEM.
      You are right that SEM involves measuring how many electrons are reflected from the surface, but as not all are reflected, that means some have been absorbed...by the heavy metals.
      Hope that makes sense?
