Understanding Emissions from a 100W Electric Lamp
When a 100W electric lamp glows, it primarily emits visible light, but it also produces other types of radiation. Among these, the most significant is infrared radiation.
Types of Radiation Emitted
- Visible Light: The primary output, allowing us to see.
- Infrared Radiation:
- Definition: A form of electromagnetic radiation with wavelengths longer than visible light.
- Heat Generation: Most of the energy consumed by the lamp is converted into heat, which is emitted as infrared radiation.
- Usage: Infrared radiation is used in various applications, including remote controls and thermal imaging.
Why Not Other Radiations?
- Gamma Radiation:
- Nature: High-energy radiation emitted by radioactive materials.
- Context: Not produced by standard electric lamps.
- Ultraviolet Radiation:
- Nature: Radiation with shorter wavelengths than visible light.
- Context: While some lamps (like fluorescent bulbs) emit UV radiation, traditional incandescent lamps do not produce significant amounts.
- X-rays:
- Nature: High-energy electromagnetic radiation.
- Context: Generated in specific conditions (like X-ray machines), not in standard light bulbs.
Conclusion
In summary, while a 100W electric lamp emits visible light, the significant additional radiation it produces is infrared radiation, making option 'B' the correct answer. This infrared emission is primarily due to the heat generated during the lamp's operation. Understanding these emissions is crucial for applications in energy efficiency and safety.
