A high-powered laser beam
Not what you're looking for?
A high power laser providing a nearly collimated beam with an average of 50 KW is used recently by the US Army as a weapon to shoot down a drone 3.6 km away. The laser beam diameter on the target is about 0.25-m after propagating such a distance.
(a) Find the average intensity at the target.
(b) Find the peak electric field E(max) and peak magnetic field B(max) of the beam at the target.
(c) Find the radiation pressure P when the laser beam is shining on the drone and is totally absorbed by the target?

Solution Summary
This solution contains step-by-step calculations to determine the laser beam, intensity, pressure, magnetic and electric fields with the given data.
Solution Preview
a. Intensity,
I = P / Area = P/ (pi*d^2/4) = 50*10^3/(pi*0.25^2/4) = 1.02 MW m^-2
b. e0 = ...

- " In question 2, you incorrectly add in the $3.00 dividend that was just paid to determine the value of the stock price using the dividend discount model. In question 4 response, it should have also been recognized that dividend discount models are not useful if any of the parameters used in the model are inaccurate. "
