1. Consult Multiple-Concept Example 5 to review the concepts on which this problem depends. A light bulb emits light uniformly in all directions. The average emitted power is 150.0 W. At a distance of 6 m from the bulb, determine (a) the average intensity of the light, (b) the rms value of the electric field, and (c) the peak value of the electric field.
2. On a cloudless day, the sunlight that reaches the surface of the earth has an intensity of about 1.4 × 103 W/m2. What is the electromagnetic energy contained in 6.0 m3 of space just above the earth’s surface?
3. The microwave radiation left over from the Big Bang explosion of the universe has an average energy density of 3.81 × 10–14 J/m3. What is the rms value of the electric field of this radiation?
4. The maximum strength of the magnetic field in an electromagnetic wave is 7.5 × 10-6 T. What is the maximum strength of the electric field of the wave?

A Review Constants Periodic Table Only about 10% of the electromagnetic energy from an incandescent lightbulb is visible light. The bulb radiates most of its energy in the infrared part of the electromagnetic spectrum. Part A If you place a 100-W lightbulb 2.1 m away from you, what is the intensity of the infrared radiation at your location? Assume that bulb radiates only visible light and infrared radiation. Express...
