Hence, at 9.0 × 1010m from the center of the Sun, we have I = Savg = 3.8 × 1026W 4π(9.0 × 1010m)2 = 3.7 × 103W / m2. Assuming the comet reflects all the incident radiation, we obtain from Equation 16.5.4 p = 2I c = 2(3.7 × 103W / m2) 3.00 × 108m / s = 2.5 × 10 − 5N / … geotaphonomy publicationsIn 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 such as acoustic waves (sound) or electromagnetic waves such as light or radio waves, in which case the average power transfer over one period of the wave is used.
