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...
