Write the range of ultraviolet waves.

(N/A) Ultraviolet $(UV)$ waves are electromagnetic waves that occupy the spectral region between visible light and $X$-rays.
The wavelength range for ultraviolet waves is approximately $1 \times 10^{-7} \, m$ to $4 \times 10^{-7} \, m$ (or $100 \, nm$ to $400 \, nm$).
