(a) What is the minimum angular spread of a 633-nm wavelength He-Ne laser beam that is originally 1.00 mm in diameter?(b) If this laser is aimed at a mountain cliff 15.0 km away, how big will the illuminated spot be?(c) How big a spot would be illuminated on the Moon, neglecting atmospheric effects? (This might be done to hit a corner reflector to measure the round-trip time and, hence, distance.) Explicitly show how you follow the steps in Problem-Solving Strategies for Wave Optics.

A. $\theta=7.72 \times 10^{-4} \mathrm{rad}$B. 23.2 $\mathrm{m}$C. 590 $\mathrm{km}$

but a off the given problem the angler separate off the laser beam is given by a sizable 1.22 times development We're going to be here is a 36 33 man a meter converting into me trice times 10 to the power of mine. It's mine minus nine. Divided by are 10 to the power minus three. Devalue this accuser Stangler support off seven point seven to times 10 to the power minus five Radiance. This is minus five radiance. Bye, Bobby. We can find a final diameter off the beam. Slight bean pointed at the mountain tape by writing X is equal Thio they, uh, d um Then the x spring we get here is my mantra plying the angle, which is 7.7 to times 10 to the power, uh, minus five times D, which is, um, five times 10 to the power of three tree. This accuse us the X off 11.58 meter, then the final diameter off light being controlled by two x plus D plus de um ignoring the D then which is approximately equal to two X, then putting the value for X, which is uh, two times off. 11.58 This gives us this gives us 23 0.2 meters. Similarly like that we did in about B in C. We can find the final diameter off a light beam by finding X to the X ray every series. Ah, 7.7 two dimes. Stinted power minus four. The angler spread off the unless a team times the d new D, which is a three point age 44 times 10 to the power eight eight. When applying these two numbers gives us here to nine six 0.27 kilometer, then we can find a final diameter off light be by proximity. You two to X, uh, went flying above number two gives us the finance super diamond trees 5 94 kilometer.
