- Based on how it refracts light, what would you expect images formed by a concave lens to look like? The same as the objects that they are images of Reversed Smaller MagnifiedAstronomers 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.The primary mirror on a telescope has a 43m radius of curvature and the eyepiece has a focal length of 36 mm. Determine the maginification and length of the telescope (for length, treat telescope as a refracting telescope) M = ___ L =______
- A telescope is used to resolve two distant stars. By what factor will the resolution of the telescope change if the diameter of the lens is doubled? a)The resolution will increase by a factor of 4 b)The resolution will increase by a factor of 2 c)The resolution will not change, although more light will be collected. d)The resolution will decrease by a factor of 2 e)The resolution will decrease by a factor of 4 f)What CANOT be explained by ray optics? the resolution of telescope. image reversal in a mirror. camera lens refraction. X the transmission of signals in fiber optic.
