So far we have worked in the time and frequency domains. We may notice that these two quantities have a specific relation: an amount of time T automatically gives a frequency f = 1/T.

Now we may ask if there are other variables like t and f, related in the same way.

For example, we can work with a space variable, like x. From now on we will move from the time-frequency domain to a new domain involving space, x, instead of t.

Working in space, by analogy with the time domain, fill the following Form.
