Intensity at a point
Nettet6. mar. 2024 · In the wave picture of light intensity of light is determined by the square of the amplitude of the wave. What determines the intensity of light in the photon picture of light? Answer: For a given frequency intensity of light in the photon, the picture is determined by the number of photons crossing a unit area per unit time. Question 24. NettetWe have to find the electric field intensity at a point P outside the spherical shell such that, OP=r. Here we take gaussian surface as a sphere of radius r. Then the electric field intensity is the same at every point of gaussian surface directed radially outwards, So, according to Gauss’s theorem
