Reflecting Telescope

(a) List some advantanges of a reflecting telescope, especially for high resolution astronomy. (b) A reflecting type telescope has a large mirror for its objective with radius of curvature equal to 80 cm . What is the magnifying power of telescope if eye piece used has a focal length of 1.6 cm ?

(a) Draw a ray diagram to show image fromation when the concave mirror produces a real, inverted and magnified image of the object (b) Obtain the mirror formula and write the expression for the liner magnification. (c) Explain two advantages of a reflecting telescope over a refracting telescope.
