Answer to Problem 45R
The denser medium has lower the speed of light.
Explanation of Solution
Introduction:
The speed of light in vacuum, commonly denoted c, is a universal physical constant important in many areas of physics. Its exact value is defined as 299792458 meters per second.
The speed of light is greater in air than in glass because density of glass is more than air. As the medium is denser the speed of light become slower. The speed of light in air is approximately
Conclusion:
Hence, the denser medium has lower the speed of light.
