A briet aser puise is fired at the moan, then the time rnorval is measured untl the "echo is seen by a telescope. A laser boam spreads out as it travols because t dtracts through a circular exit as it leaves tha laser. In order for the refleched sight to be bright enough la detect, the laser spot on the moon must be no more than 1.0 km in diamoter. Staying within this diameher is accomplished by using a special lage-diameler laser Part A It A 515 nm, what is the mninum dameter ot the crcular opening from which the laser emerges? The earth-moon distance is 384 000 km Express your answer to two significant figures and include the appropriate units. through a circ D-1 Value Units Raquest Answ Raturm to Assignment Pronde Feedbacik ere to search 8 3 AltExplanation / Answer
Given,
Wavelength, lambda = 515 nm
Maximum W= 1000 m
Distance L = 384*10^6 m
Diameter of the central maximum W,
W = 2.44 lambda L/d
d = (2.44 x 384*10^6 x 515*10^-9)/ 1000
W = 0.48 m (Ans)
