using a plane wave model, estimate the following quantities
a)the magnitude of the electric and magnetic fields in a 5 mw hene (\lambdao=633 nm) laser beam in air. assume the power is ~evenly distributed in a beam of diameter ~0.5 mm. b) the intensity (irradiance is becoming the more accepted term, actually) of a co2 (\lambdao=10.6 \mum) laser beam at a focal point that is causing air breakdown. use the low frequency breakdown strength of air, ~3 x 106 v/m.
c) the electric field magnitude in a nd-glass laser beam, with \lambdao=1.06 \mum, which is producing 5.2 kj pulses with a duration of 0.8 ns. assume the beam is focused to a spot with diameter of 0.2 mm (in air).

Why does the equilibrium position of the spring change when a mass is added to the spring? will the mass oscillate around the new equilibrium position of the spring or the previous position without a mass attached to the spring? if the equilibrium position of the spring changes by 20 cm (assuming no initial mass) when a mass is added to the spring with constant 4.9 kg/s^2, what is the mass of the object attached to the spring?
