Galileo’s telescopes, II. The characteristics that follow are characteristics of two of Galileo’s surviving double-convex lenses. The numbers given are magnitudes only; you must supply the correct signs. L1: front radius = 950 mm, rear radius = 2700 mm, refractive index = 1.528; L2: front radius = 535 mm, rear radius = 50,500 mm, refractive index = 1.550. (a) What is the largest angular magnification that Galileo could have obtained with these two lenses? (b) How long would this telescope be between the two lenses?

An amateur astronomer has a telescope to examine distant stars and nebulae. The focal length of the main objective lens of the telescope is f= 710 mm. At what distance from the lens will a distant star be imaged using this objective lens? Give your answer in units of metres.arrow_forward2. Derive the lens maker's formula using paraxial optics. 1/f = (n-1)(1/R_1 – 1/R_2), where n is the index of refraction for the glass, and R_1 and R_2 are the radii of curvature for the two sides of the lens, and f is the focal length.arrow_forward

- 2. If a telescope with focal length 30 cm "sees" an object taking up 2° of its view, how big is the image in the telescope? 3. If an object makes an image that's 0.5 mm on your retina, how many degrees of your view does it occupy? 4. When you zoom into an object optically with your camera (not electronic zoom), does the lens extend or contract? Why? 5. Why is a ground-based x-ray telescope not a great idea? 6. What is the resolution in seconds of telescope with a 0.5 m diameter lens at visible light? 7. Some telescopes are dual-purpose: they detect visible light and infra-red. Were the telescope in the question above capable of this, would it have higher resolution in infra-red or lower (compared to visible light)? 8. What diameter lens do you need on a telescope that can resolve up to a thousandth of a second? 9.
