THIS IS A PROBLEM OF PHYSICS MECHANIC, PLEASE READ CAREFULLY THE ATTACHED FILE.<span />
You have to draw a mathematical spatial axes .in order to judge is it right or not .. well you have to draw the crest and trough both of 1 cm in length and the total wavelength (same phase on the wave of 2 cm ) something like this
Vas happenin!!

Hope this helps *smiles*
Answer:
The potential energy is
Explanation:
From the question we are told that
The inner radius is
The outer radius is
The common length is
The potential difference is
Generally the capacitance of the cylindrical capacitor is mathematically represented as
Where is the permitivity of free space with the values
and k is the dielectric constant of the dielectric material here the dielectric material is free space so k = 1
Substituting values
The potential energy stored is mathematically represented as
substituting values
In the part of the spectrum our eyes can detect (a spectrum is an arry of entities, as light waves or particles, ordered in accordance with the magnitudes of a common physical property, as wavelength or mass) Hope this helps you :D
