Exam-style question
Try this first
Explain how electromagnetic wave theory relates to the speed of light.
Model answer
What a good answer should say
- Electromagnetic wave theory states that light travels as waves of oscillating electric and magnetic fields.
- The speed of light in a vacuum is approximately 3.00 x 10^8 m/s, which is derived from the properties of these waves.
Explanation
Why this works
This answer is strong because it directly connects the theory of electromagnetic waves to the established speed of light, demonstrating an understanding of both concepts. The question tests the student's ability to articulate the relationship between wave theory and the speed of light.
