- I 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 viewarrow_forwardMagnifying glass. Relaxed vision. Now lets’ consider relaxed vision, i.e. assume that the image is formed at infinity and do ≈ f (see the figure). Determine its magnification M = θ / θ’ in terms of the focal length f and N.arrow_forwardThe telescope and CCD detector described in question 2 are used to observe a distant star cluster. The detector has 2000 x 2000 pixels. What is the minimum angular separation between two stars in the cluster that can just be resolved with this observing system if we ignore the effects of diffraction and the Earth's atmosphere? Assume the two stars are resolved if they are able to fall on the centres of two neighbouring pixels. Choose the answer below that best matches your answer. Select one: Оа. 2.5" O b. 0.07" O C. 0.15" d. 1.3" е. 0.80"arrow_forward
- Astronomers who use ground-based telescopes spend a lot of time and effort dealing with something called seeing. Sometimes they build adaptive-optics systems to try and partially overcome it. What is seeing? Group of answer choices Stray light from buildings, cars, parking lots, streetlights, etc.., which makes the night sky brighter and thus makes it harder to see faint astronomical objects The inability of refracting telescopes to bring all colors of light to a focus at the same distance from the objective lens. Turbulence in the Earth's atmosphere that makes for blurry images of astronomical objects The ability of a spectrograph or spectrometer to spread light out into its constituent colors, thus revealing what a distant object is made of.arrow_forwardSuppose that two stars are separated in the sky by 0.2 arcsecond. If you look at them with a telescope that has an angular resolution of 0.5 arcseconds, what will you see? A. one point of light that is the blurred image of both stars B. two distinct stars C. nothing at all D. This can't be answered without knowing the size of the telescope.arrow_forwardA sharp image of a pencil that’s 25 cm away from your eye is formed on your retina. As you move the pencil farther away from your eye, your eye can still form a sharp image of the pencil on your retina at 50 cm, 75 cm, 100 cm, 125 cm, 150 cm, 175 cm... but fail when it is 200 cm away. Are you nearsighted or farsighted? farsighted nearsighted both nearsighted and farsighted not enough information neither nearsighted nor farsightedarrow_forward
- A severely myopic patient has a far point of 3.35 cm. By how many diopters should the power of his eye be reduced in laser vision correction to obtain normal distant vision for him? (Assume a lens-to-retina distance of 2.00 cm.) Additional Materials O Readingarrow_forwardDiscussion: 1- Define refraction index? What its depending parameters? Value for air and water? 2- Define with physical units and relationships if founded: Critical angle- Compound lens - Parallax eliminating Lens Maker's equation- Total Internal Reflcction (TLR) - Sncll's Law?. 3- What are Real width and Virtual width?. 4- What Optical Density? Is high Mass Density effect?, Explain with exaruples?. 5- Is thickness of media effected to refiaction index?, Why?. 6- What difference between ice and water refaction index? Which larger? Why?. 7- In experiment- part one, can you find refraction index of oil? Why?. 8- Prove sia i, AC 9- Prove AC Real Widtlh 10- prove %3D 5-5 Virted Widtharrow_forwardIf you wear corrective lenses, one option is to get laser vision corrective surgery.
