Question

Alpha Centauri, the nearest star to our solar system, is 4.3 light years away. Assume that Alpha Centauri has a planet with an advanced civilization. Professor Dhg, at the planet's Astronomical Institute, wants to build a telescope with which he can find out if there are planets orbiting our sun. What is the minimum diameter for an objective lens that will just barely resolve Jupiter and the sun? The radius of Jupiter's orbit is 780 million km. Assume lambda = 600nm. Express your answer to two significant figures and include the appropriate units. d_min = 3.8 cm Building a telescope of the necessary size does not appear to be a major problem. What practical difficulties might prevent Professor Dhg's experiment from succeeding? Essay answers are limited to about 500 words (3800 characters maximum, including spaces). 3800 Character(s) remaining

Explanation / Answer

(B)

When, we compare the brightness of light of sun to the reflected light from jupiter,

it appears to be diminished.

Theoretically it may be possible to resolve, But practically, due to high brightness of sunlight,

lt is not possible.

So, lt might prevent professor Dhg's experiment from succeeding.
