Distance and time mostly go together. And speed also goes along with these two. Below are some equations related to distance and time: Time = Distance / Speed Distance = Time * Speed Speed = Distance / Time From this we can see that if any one of these three measurements are changed, one of the other two or both will always change.
The principle involved in wedge film is interference.

A laser rangefinder uses a laser to determine the distance to an object. The principle used is the time of flight principle based on the speed of light.
This is the Archimedes principle.

i think the answer is that {it is my own thinking answer} when light enter from air to water it bent because it want follow a principle which is light take same time to travel in same distance in air and water therefore when it enter water it reduce speed so obiviously it take more time to travel a given distance then in air so to follow the principle that it take same time time to travel in air and water ,light bent inorder to decrease distance so by decreasing distance it will take same time
