I have an electromagnetic wave propagating in a material (e.g. Silicon) at a known frequency and I would like to find the wavelength.
The general formula is:

\[ \lambda = \frac{v}{f} \]

since \[ \mu * E \]
If I do not know the electric field ... I will assume it ??

In the case of silicon, I found the following parameters on the internet:
Mobility electrons = 1000 cm2/ (V⋅s)
E = 3*10^5 V/cm

can I use these for the calculation?
