a) A microscpe objective with a 5 mm focal length is used toproject the image of an illuminated object 0.1mm high onto a screen1m from the objective. what is the height of the image?
b) the objective in now placed into a microscope and the imageis projected onto a screen 1m above the objective using a 10xeyepeice. if the eyepeice is 19cm away from the objective what isthe height of the image? is it upright or inverted?
