Question
In which material do you think light rays travel faster-glass or air?
Advertisements
Solution
The speed of light in an optically rarer medium is more than the speed of light in a denser medium. Now, air is an optically rarer medium and glass is a denser medium. Therefore, light rays will travel fast in air.
