Question
Light travels a distance of '10x' units in time 't1' in vacuum and it travels a distance of 'x' units in time 't2' in a denser medium. Using this information answer the question that follows:
'Light covers a distance of '20x' units in time 't1' in diamond'. State true or false.
Options
True
False
Solution
This statement is False.
Reason:
Because light always travels slower in a medium than it does in a vacuum. Within a vacuum, light travels 10x units over time 't1'. Therefore, it is impossible to travel '20x' units in time 't1' in a diamond.
