draw a ray diagram for this A concave mirror with a focal length of 10.0 cm creates a real image 30.0 cm away on its principal axis; the corresponding object is located how far from the mirror? Use the mirror equation: 1/di + 1/do = 1/f where di = +30 cm and f = +10 cm. Substitute and solve for do. 1/do + 1/(30 cm) = 1/(10 cm) 1/do = 1/(10 cm) - 1/(30 cm) = 2/(30 cm) do =...

A Galilean telescope is made with a 40 cm focal length objective lens and a -10 cm focal length eyepiece. As is typical, the separation between the lenses is the sum of the focal lengths, i.e. 30 cm. Usually this telescope would be used to view far distant objects, but suppose the object viewed is only three focal lengths (120 cm) distant from the objective lens (a) On the figure above, sketch the principal rays that determine the size and location...
