f = c / λ = wave speed c (m/s) / wavelength λ (m). The formula for time is: T (period) = 1 / f (frequency). λ = c / f = wave speed c (m/s) / frequency f (Hz). The unit hertz (Hz) was once called cps = cycles per second.
An easy way to remember the distance, speed and time equations is to put the letters into a triangle. The triangles will help you remember these 3 rules: Distance = Speed x Time. Time = Distance/Speed.
distance/speed=1/λ = (20 m/s)/5 Hz
Distance Speed Time Formula. Speed is a measure of how quickly an object moves from one place to another. It is equal to the distance traveled divided by the time. It is possible to find any of these three values using the other two.

There is No Such Thing as Time – Never Was and Never Will Be

Everything exists in the present moment and it’s a fundamental principle of the Universe that many of our scientists are still trying to grasp. Time does not actually exist and Quantum Theory proves it.
There are things that are closer to you in time, and things that are further away, just as there are things that are near or far away in space. But the idea that time flows past you is just as absurd as the suggestion that space does.
The trouble with time started a century ago, when Einstein’s special and general theories of relativity demolished the idea of time as a universal constant. One consequence is that the past, present, and future are not absolutes.
Einstein’s theories also opened a rift in physics because the rules of general relativity (which describe gravity and the large-scale structure of the cosmos) seem incompatible with those of quantum physics (which govern the realm of the tiny).
According to Einstein’s special theory of relativity, there is no way to specify events that everyone can agree happen simultaneously.
Two events that are both “now” to you will happen at different times fo
