Answer #1

We have the equation for the angular resolution of an interferometer ,

Angular resolution

R = (.25 *106 *wavelength)/ Distance

Here wavelength = 1 cm = 1*10-²m

Distance D = distance between earth and moon.

D= 384000km = 384000*10³ m

So R =0.25 *106*1*10-²/(384000*10³)

R= 6.51*10-6

    (a) A simple telescope demo: We need to build this from scratch. We have an eyeglass lens to get started, which we could use as our eyepiece lens; we would need to buy an objective lens and a cardboard tube (from our favorite online marketplace). Assuming the eyeglass lens is a converging one and has focal length f, what type of objective lens do we need if we would like the telescope to have a magnification factor of 100? What...

    Telescopes that observe nonvisible types of light work on the same principles as visible telescopes, but they might require different technologies. For instance, instead of lenses or mirrors, a radio telescope (such as the one in the figure) uses technology similar to the television satellite dish you might install on your roof. As with visible light telescopes, bigger radio telescopes yield greater light-gathering power and better angular resolution. However, the angular resolution (θ) of a telescope also depends on the...

    Problem Four You should attempt this problem after Lecture 6 Cycle 3 The moons gravitational influence on the earth cause the tides, which dissipates the kinetic energy of the earth-moon system. As a consequence the earth's rotation is slowing and the moon moves away from the earth at a rate of 3.84 cm each year (same speed your fingernails grow at). At some point in the earths future it is possible that the moons orbit will correspond to the time...

    Suppose we are thinking about replacing an old computer with a new one. The old one cost us $1,740,000; the new one will cost, $2,105,000. The new machine will be depreciated straight-line to zero over its five-year life. It will probably be worth about $495,000 after five years. The old computer is being depreciated at a rate of $384,000 per year. It will be completely written off in three years. If we don’t replace it now, we will have to...
