it allows only a reduced number of electrons to flow through it.
We know,
V= f× wavelength
10.5= f×0.15
f=10.5/0.15
f= 70 Hz
<span>Epsilon
zero is permittivity of free space means how much air or vacuum permits
electric field to travel from one charge to other.It is constant in the coulomb
law. This allow Gauss's a lot easier to solve rather than using K</span>
I believe it is noise pollution
