Describe the relationship between the speed of light and electromagnetic waves.
Model answer
What a good answer should say
- The speed of light in a vacuum is approximately 3.00 x 10^8 m/s, which is the speed at which electromagnetic waves propagate.
- This speed is constant and is a fundamental property of electromagnetic radiation.
Explanation
Why this works
This answer highlights the importance of the speed of light as a constant in physics and its role in the behavior of electromagnetic waves. It tests the student's recall of key concepts related to wave propagation and the nature of light.
