The given 2.6 µC of charge is due to a buildup of electrons, each of which has a charge of 1.6 x 10^-19 C. The 2.6 <span>µC is equivalent to 2.6 x 10^-6 C, so we can divide this by the individual charge of an electron:
</span>2.6 x 10^-6 C / 1.6 x 10^-19 (C/electron) = 1.625 x 10^13 electrons
For light travelling in vacuums, ALWAYS use this equation:
c = (wavelength) * (frequency)
c is a constant, speed of light = 3 x 10^8 m/s
make sure all units are consistent!
so frequency = c / (wavelength) = ( 3 x 10^8 m/s ) / (4.257 x 10^ -9 m )
plug it into your calculator and you're done!
