Impedance of a coil or a capacitor does depend on the excitation frequency,
but resistance has no relationship to frequency.
the wavelength of the wave get smaller, decreases because the frequency is doubled, increasing..vise versa.
The speed halves.
The speed halves.
That has no effect on the resistance. The current doubles also.
Nothing happens

It is halved. coz voltage=current * resistance

Wavelength = 1/frequency. If you double the frequency, the wavelength drops to half.
The frequency also doubles of the wave length stays the same. Remember that Velocity = (the wavelength) x (the frequency)
resistance is directly proportional to wire length and inversely proportional to wire cross-sectional area. In other words, If the wire length is doubled, the resistance is doubled too. If the wire diameter is doubled, the resistance will reduce to 1/4 of the original resistance.
