Assuming a laser source, write out the equations for the lateral resolution and axial resolution for a confocal imaging system (assume incident beam waist wi, lens focal length f, and wavelength ? -800nm). for the axial resolution, you can use twice the rayleigh range of the beam. b) next, write out the equations for the lateral resolution and axial resolution for an oct system. consider the same beam, lens, and wavelength parameters as for case 'a'. in addition, assume that the laser has a coherence length of 100nm c) for low na (0.01 na), which system has the higher axial resolution? how about for high na (approaching 1 na)? at what na do the two systems have approximately equal axial resolution?

a high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. a low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air.

in general, areas that experience high atmospheric pressure also experience fair weather. low pressure systems can cause the formation of clouds and storms. air usually flows from areas of high pressure to areas of low pressure..

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.
