    b) explain the terms and their significance
    (a) They refer to the 2 fibre obtic cables inside the endoscope
    (b) One of the cables is to see what is inside the person. This cable is coherent, so the bundle of fibres inside the cable are in the same position at each end. This lets you see the picture of the person's insides.

    The other fibre obtic cable is to shine light inside the person. This cable is non-coherent - it doesn't matter if the fibres aren't in the same position at each end of the cable because it is just used to provide light.
