<EDIT> Actually, no. If it was a
wave length of 1 second, the frequency would be 1 divided by 1, or 1Hz.
As it is, it's the pulse "width" (only a
portion of the wavelength). In this circuit,
the frequency is set by the trigger timing, which you can't see yet. The answer is set out below.
OK. Here we go...
Here's the pulse circuit and its setup and correct displays (
pay very close attention to ALL setup options):

See if you can work out the frequency of the output signal. Remember the "wavelength" is the time between the start (trigger) of a wave (pulse, in this case) and the start of the
next trigger.
Don't let the wave "shape" throw you. It's still a "wave".
Also note the pulse "width", which was determined by the RC circuit.
Keep in mind that the
frequency was set by the Timed Switch "Period" setting.
BTW, "period" in another term used for wavelength. Yeah, I know, "not another term. CBB!!?" Yup. You'll see this tendency to use multiple terms for the exact same thing
often in electronics.
BTW, it's OK to have frequencies
below 1Hz.
Enjoy. Don't hesitate to play with R1 and C1 values and observe the generated pulse changes.
