- All these can be explained by ray optics EXCEPT: a) the resolution of telescope. b) the transmission of signals in fiber optic. c) image reversal in a mirror. d) camera lens.If a telescope is 10 times bigger in diameter it will gather _________ times more light than a smaller telescope2. Write down the nature of the images for the astronomical telescope, Galilean telescope and the micro- scope. Are the images inverted? Erect? Real? Virtual?
- Which one of the following would you suggest to an astronomer to best resolve two closely spaced stars? Use a large objective lens and observe using blue light Use a large objective lens and observe using red light Use a small objective lens and observe using blue light Use a small objective lens and observe using red lightInstead of a dot, sometimes the telescope image of a star looks like concentric rings. This is due to: a)diffraction. b)reflection. c)refraction. d)scatter.what three astronomical objects are represented on this excerpted Image 1 from a postage stamp? What are the two rings?
