Show that angular magnification m is also given by equation

Reference no: EM13336887

Isaac Newton, having convinced himself (erroneously as it turned out) that chromatic aberration was an inherent property of refracting telescopes, invented the reflecting telescope. He presented his second model of this telescope, which has a magnifying power of 38, to the Royal Society, which still has it. Incident light falls, closely parallel to the telescope axis, on the objective mirror M. After reflection from small mirror M', the rays form a real, inverted image in the focal plane through F. This image is then viewed through an eyepiece.

Show that the angular magnification m(theta) is also given by the equation:

m(theta) = -f(objective) / f(eyepiece)

The words in the brackets are subscripts.
