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?

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

                                              ⇒      

here   k is the proportionality constant whose value is 1.

                                                            [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.
