Consider a wave that is a superposition of two hermite-gaussian beams of order (1,0) and (0,1) with equal intensities. the two beams have independent and random phases so that their intensities add with no interference. show that the total intensity is described by a donut-shaped circularly symmetric function. assume that wo 1, determine the radius of the circle of peak intensity and the radii of the two circles with 1/e2 time the peak intensity at the beam waist.

explanation: in any substance/object, the particles inside it (atoms/molecules) constantly move in random directions and with random speeds (this motion is called brownian motion). as a result, the particles have some kinetic energy (which is proportional to the temperature of the substance).

explanation:

have a great day!

radiation warms things up temp rises convection currents air circ windy weather

causes

fossil fuels burn

cities become more industrialized

human population grows worldwide
