The correct Answer is:
**Step-by-Step Solution:** 1. **Identify the Scientist and Experiment**: The question asks about T.W. Engelmann, who is known for his experiment related to photosynthesis and light. 2. **Understanding the Experiment**: Engelmann conducted an experiment to determine which wavelengths of light are most effective for photosynthesis. 3. **Light Splitting Method**: To split light into its components, Engelmann used a **prism**. A prism can refract light and separate it into its constituent colors (spectrum). 4. **Use of Algae**: Engelmann used a type of green algae called **Cladophora** in his experiment. He placed this algae in the path of the split light. 5. **Observation with Aerobic Bacteria**: Engelmann introduced aerobic bacteria to the setup. He observed that these bacteria accumulated in areas where blue and red light were present. 6. **Conclusion**: From his observations, Engelmann concluded that blue and red light are the most effective wavelengths for photosynthesis, as indicated by the accumulation of aerobic bacteria in those light regions. 7. **Final Answer**: Therefore, T.W. Engelmann split the light into its components using a **prism**. ---
