The wavelength ($\lambda$) of a signal can be calculated using the formula $\lambda = \frac{c}{f}$, where $c$ is the speed of light ($3 \times 10^8$ m/s) and $f$ is the frequency of the signal. For a 200 THz (terahertz) signal, $f = 200 \times 10^{12}$ Hz. Thus, $\lambda = \frac{3 \times 10^8}{200 \times 10^{12}} = 1.5 \times 10^{-6}$ meters, or 1500 nm.
