$0.44$ $0.44$ $μ m$ $mu m$

Explanation:

$speed = wavelength \times frequency$ $"speed" = "wavelength" xx "frequency"$

$wavelength = \frac{3 \cdot 10^{8}}{6.81 \cdot 10^{14}} = (0.44 \cdot 10^{- 6}) m$ $"wavelength" = (3*10^8) /(6.81*10^14) = (0.44 * 10^(-6))"m"$

$= 0.44$ $= 0.44$ $μ m$ $mu "m"$
