Frequency changes wavelength, pulse length, and axial limit. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.
highlighted = computed this step
Frequency changes wavelength before the pulse limit
The speed and cycle count stay fixed; the scan changes only frequency.
λ=fc,Δd=2Nλ
Three frequencies give three pulse-length limits
Higher frequency shortens wavelength, pulse length, and the axial limit.

The middle row has a four-meter limit
The final display follows the same checked wavelength and cycle count as the diagram.
