8 0

Although green light has a lower frequency than the blue light, but green light has the longer wavelength than the wavelength of blue light. The wavelength of green light is longer by a small margin than the wavelength of the blue light. Red light has the highest wavelength among all the available colors of light. Any color of light is nothing but an electromagnetic wave that enables us to see things around us. Humans mostly can see wavelengths between the Electromagnetic spectrum and the Ultra violet region.

The linear charge density on the inner conductor is and the linear charge density on the outer conductor is

Lubov Fominskaja [6]

Complete Question

The complete question is shown on the first uploaded image (reference for Photobucket )

Answer:

The electric field is $E = -1.3 *10^{-4} \ N/C$

Explanation:

From the question we are told that

The linear charge density on the inner conductor is $\lambda _i = -26.8 nC/m = -26.8 *10^{-9} C/m$

The linear charge density on the outer conductor is

$\lambda_o = -60.0 nC/m = -60.0 *10^{-9} \ C/m$

The position of interest is r = 37.3 mm =0.0373 m

Now this position we are considering is within the outer conductor so the electric field at this point is due to the inner conductor (This is because the charges on the conductor a taken to be on the surface of the conductor according to Gauss Law )

Generally according to Gauss Law

$E (2 \pi r l) = \frac{ \lambda_i }{\epsilon_o}$
