Design an argon ion laser cavity such that the following criteria are met. the argon ion laser is a gas i. discharge device that lases at 488 nm. a) the far field divergence is 1 mrad( half angle). b) the longitudinal mode spacing (free spectral range) is 500 mhz provide: i. a sketch of the system il. supporting calculations that the system performs to specifications iii. supporting calculations that the system is stable iv. find: what are the spot sizes on the cavity mirrors?

Ihave no idea sorry

Answer: 1.4 seconds which is the third optionexplanation: current is defined as the flow of charge per timetherefore, the equation that relates current, charge and time can be expressed as follows: i = δq / δtwhere: i is the current given = 1.8 ampereδq is the charge given = 2.5 coulombδt is the time required for the flow of the given charges to give the 1.8 ampere.substitute with the givens in the above equation to get the time as follows: 1.8 = 2.5 / δtδt = 2.5 / 1.8 = 1.38888 which is approximately 1.4 secondshope this was !

Gotta have a picture ^^

Well it depends on the object or substance
