Hi, I was reading an article about translucency and trasmittance and the term reflectivity contrast came up. Does anyone know what this may mean?

what I am confused is when they say, charge is microfarad does that mean q=2x10^-6 or is the capacitor 2 microfarad meaning c=2x10^-6

Homework Statement The charge on a 2-microfarad capacitor is given by q(t)=10^-6 * sin(10^5*t) C find the dexpression for the voltage and current? Homework Equations The Attempt at a Solution the answer is v(t)=0.5sin(10^5t) , i(t)=0.1cos(10^5t) i don't get how they found the answer
