T.W. Engelmann split the light inot its components using a

Options

A. green glass
B. convex lens
C. prism
D. concave lens

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the method used by T.W. Engelmann to split light into its components.

2. **Identifying the Options**: The options provided are:
- A) Green glass
- B) Convex lens
- C) Prism
- D) Concave lens

3. **Recalling Engelmann's Experiment**: T.W. Engelmann conducted experiments to study photosynthesis. He needed to split light into its various components to observe how different wavelengths affected photosynthesis.

4. **Selecting the Correct Tool**: Engelmann used a **prism** to split the light into its spectral components. A prism refracts light and separates it into its constituent colors.

5. **Conclusion from the Experiment**: Engelmann observed that the accumulation of aerobic bacteria was highest in the blue and red regions of the light spectrum, indicating that these wavelengths were most effective for photosynthesis.

6. **Final Answer**: Based on the above reasoning, the correct answer to the question is **C) Prism**.
