The correct Answer is:
To solve the question "Light energy emitted by a star is due to," we need to analyze the options provided and understand the processes occurring within a star. ### Step-by-Step Solution: 1. **Understanding Stellar Processes**: - Stars generate energy through nuclear reactions. The primary process in stars like our Sun is nuclear fusion, where lighter atomic nuclei combine to form heavier nuclei. 2. **Evaluating the Options**: - **Option 1: Breaking of nuclei** - This refers to nuclear fission, which is not the primary process in stars. - **Option 2: Joining of nuclei** - This describes nuclear fusion, where hydrogen nuclei combine to form helium, releasing energy. - **Option 3: Burning of nuclei** - This is not a scientifically accurate term in the context of nuclear reactions. - **Option 4: Reflection of solar light** - This does not pertain to the generation of light energy within the star itself. 3. **Identifying the Correct Process**: - The process that occurs in stars involves the joining of lighter nuclei (like hydrogen) to form heavier nuclei (like helium). This fusion releases a significant amount of energy in the form of light and heat. 4. **Conclusion**: - Therefore, the correct answer to the question is **Option 2: joining of nuclei**. ### Final Answer: Light energy emitted by a star is due to the joining of nuclei. ---
