- please answer vSimilar to the above question, I have a refracting telescope with an objective lens focal length f=200 mm. I have three possible eyepiecesI can use with this telescope, having focal lengths of 9 mm, 25mm and 50 mm. I want to look at a cluster of stars which are well spread apart from each other on the sky. Which eyepiece would I best use for this? A. 9 mm B. 25 mm C. 50 mm D. It doesn't matter which oneI need help with this homework I’m trying to figure out what will give better resolution. Two lenses with numerical aperture of 1 and 1.25 are used to view a specimen using light that has a wavelength of 600nm. Which one will give better resolution Of all the objective which lens has maximum distance and which one has minimum field of view

An optical filter can be described by the Jones vector [. cos a sin a sin a cos² a cos a sin a (a) Obtain the form of the emerging beam when the incident light is plane poloarized at angle 0 to the horizontalTwo stars are 3.6 × 10¹1 m apart and are equally distant from the earth. A telescope has an objective lens with a diameter of 1.66 m and just detects these stars as separate objects. Assume that light of wavelength 520 nm is being observed. Also, assume that diffraction effects, rather than atmospheric turbulence, limit the resolving power of the telescope. Find the maximum distance that these stars could be from the earth. Number i UnitsHi, please show full solutions and also explain how you get the answers in physics terms so it's understandable. The correct final answers are written beside too. This is one whole question to be answered, please. I can't post it separately since it's related. Thank you.
- Two stars located 21 light-years from Earth are barely resolved using a reflecting telescope having a mirror of diameter 66 cm. Assuming ? = 550 nm and assuming that the resolution is limited only by diffraction, find the separation between the stars. mProblem 4 Lenses are often coated with thin films of transparent substances such as MgF2 (n=1.38) to reduce the reflection from the glass surface. How thick a coating is needed to produce a minimum reflection_at the center of the visible spectrum (A=550 nm)? Air Glass MGF2 n2 = 1.38 ng 1.50 n1 = 1.00 Given: A-550 nm 12 n=1.38 Minimum reflection: a (Destructive interference) Thickness of coating: d=?The nonreflective coating on a camera lens with an index of refraction of 1.23 is designed to minimize the reflection of 625-nm light. If the lens glass has an index of refraction of 1.51, what is the minimum thickness of the coating that will accomplish this task? X Your response differs from the correct answer by more than 10%. Double check your calculations. m

A) For 548-nm light, what minimum thickness of MgF2 will cause the reflected rays R2 and R4 (see figure) to interfere destructively, assuming normal incidence? Express your answer to three significant figures. B) Interference will also occur between the forward-moving rays R1 and R3 in the figure. What minimum thickness of MgF2 will cause these two rays to interfere constructively? Express your answer to three significant figures.A nearsighted woman has a far point of 280 cmcm .
