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.1. If you place a 100-W lightbulb 2.2 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.
2. What is the average infrared energy density?
3. What is the approximate magnitude of the infrared electric field?
4. What is the approximate magnitude of the infrared magnetic field?
