Homework Statement
for my assignment given i was told to derive the equation of the skin depth of a good conductor and i derived it as
d=sqrt(2/[itex]\mu\omega\sigma[/itex])
then i was told to calculate d where i was given w=10^15 and sigma=10^7 and this gave me a d of d=1.26E-8 which i guess is a small skin depth and then i was given the question:
From this result, explain why good conductors are opaque to visible light?
i know the skin depth represents the depth of the material the wave has to travel before it reaches 1/e of its original value but i don't know how to answer this question.
