Define Newton's corpuscular theory of light and the wave theory of light. What is the key difference between these two explanations?.
Model answer
What a good answer should say
- Newton's corpuscular theory of light posits that light is made up of particles called corpuscles that travel in straight lines.
- In contrast, wave theory suggests that light behaves as a wave, exhibiting properties such as interference and diffraction.
- The key difference is that corpuscular theory emphasizes particle-like behavior, while wave theory focuses on wave-like behavior.
Explanation
Why this works
This question tests the understanding of two fundamental theories of light. By defining both theories and identifying their key difference, students demonstrate their grasp of the concepts and their ability to compare and contrast different scientific explanations.
