Answer:
The ratio of the speed of light in glass to the speed of light in a vacuum is 2:3.
Explanation:
Given that,
Speed of light in vacuum = 186000 miles/sec
Speed of light in glass = 124000 miles/sec
We need to calculate the ratio of the speed of light in glass to the speed of light in a vacuum
The ratio of speed of light in glass to the vacuum
[tex]\dfrac{v_{g}}{v_{a}}=\dfrac{124000}{186000}[/tex]
Where, [tex]v_{g}[/tex] = speed of light in vacuum
[tex]v_{a}[/tex] = speed of light in vacuum
[tex]\dfrac{v_{g}}{v_{a}}=\dfrac{2}{3}[/tex]
Hence, The ratio of the speed of light in glass to the speed of light in a vacuum is 2:3.
