Answer:
1/3 times.
Explanation:
Let V₀ be the peak voltage .
IR ( rms ) = ( V₀ / √2 R )
R is value of resistance
IC = ( V₀ ωC / √2 )
( 1 / ωC is reactance of capacitance in ac circuit )
=
When frequency is tripled angular frequency will also be tripled
hence the ratio becomes 1/3 times.
The wavelength will remain unchanged.
Explanation:
The velocity of a wave in terms of its wavelength
and frequency
is
(1)
so if we double both the velocity and the frequency, the equation above becomes
(2)
Solving for the wavelength from Eqn(2), we get
We would have gotten the same result had we used Eqn(1) instead.
