A strong light bulb radiates light in all directions. The average power of the EM waves by this bulb is 1910.0 W
A strong light bulb radiates light in all directions. The average power of the EM waves by this bulb is 1910.0 W. At a distance r = 0.6 m from the bulb, the EM waves spread over a surface area of 4πr2
(a) Calculate the Average Intensity. Keep 1 decimal place.
(b) Calculate the Average Energy Density (including both the electric field and the magnetic field). Write the result in terms of 10-5J/m3. Keep 4 decimal places.
(c) Calculate the Average (rms) Electric field. Round to integers.
(d) Calculate the Peak Electric field. Round to integers.
New situation: the new PEAK Intensity is 1215.9 W/m2, calculate the new PEAK Electric field. Round to integers.
