Answer: The frequency is inversely related to wavelength in electromagnetic wave.

Explanation:

Relationship between the frequency and wavelength of wave is given by the equation:

$\nu=\frac{c}{\lambda}$

where,

$\nu$ = Frequency of the wave

c = speed of light = $3\times 10^8m/s$

$\lambda$ = Wavelength of the wave

From the above relation, it is visible that frequency is inversely related to the wavelength of the wave.

Higher the frequency, low will be the wavelength of the wave and vice-versa.

The Nichrome wire is replaced by a wire of the same length and diameter, and same mobile electron density but with electron mobi

Marina CMI [18]

Answer:

The electric field inside the wire will remain the same or constant, while the drift velocity will by a factor of four.

Explanation:

Electron mobility, μ = $\frac{v_d}{E}$

where

$v_d$ = Drift velocity

E = Electric field

Given that the electric field strength = 1.48 V/m,

Therefore since the electric potential depends on the length of the wire and the attached potential difference, then when the electron mobility is increased 4 times the Electric field E will be the same but the drift velocity will increase four times. That is

4·μ = $\frac{4*v_d}{E}$
