Solution From Equation 16.31, the intensity of the laser beam is I = 1 2cε0E20. The amplitude of the electric field is therefore E0 = √ 2 cε0I = √ 2 (3.00 × 108m/s)(8.85 × 10−12F/m)(1.0 × 10−3W/m2) = 0.87V/m.

Intensity Formula Definitions & Solved Example Questions

In physics, the intensity or flux of radiant energy is the power transferred per unit area, where the area is measured on the plane perpendicular to the direction of propagation of the energy. In the SI system, it has units watts per square metre (W/m ), or kg⋅s in base units. Intensity is used most frequently with waves … Se mer In photometry and radiometry intensity has a different meaning: it is the luminous or radiant power per unit solid angle. This can cause confusion in optics, where intensity can mean any of radiant intensity, luminous intensity Se mer • Field strength • Sound intensity • Magnitude (astronomy) Se mer NettetBecause work W is related to force multiplied by distance ( Fx) and energy is put into the wave by the work done to create it, the energy in a wave is related to amplitude.
