Finding Electric & Magnetic Field Energy Densities in a Dielectric Medium

AI Thread Summary
To find the power dissipated per unit volume, electric field energy density, and magnetic field energy density in a perfect dielectric medium, standard equations from electromagnetic theory can be utilized. The electric field E and magnetic field H are given, allowing for the calculation of the power flow density vector using the Poynting vector formula P = E x H. The specific equations for energy densities can be found in basic electromagnetic wave literature or online resources. The discussion emphasizes the need for clarity on these equations to complete the assignment due today. Understanding these concepts is crucial for solving the problem effectively.

If current densities are given in a perfect dielectric medium having \epsilon , \mu
I have to find the power dissipated per unit volume, the electric field energy density, and the magnetic field energy density everywhere.
Can I get help with equations?

These are standard equations (outcomes of electromagnetic theory) and you should be able to find them even in a basic treatment of electromagnetic waves (for example, in books like Krane, Sears/Zemansky, etc). You could even search on google.com. What is your specific trouble with them?
 
Given
E=J_{so}cos(\omega t-\beta z) \vec{i}
and
H=\frac{J_{so}}{2}cos(\omega t-\beta z) \vec{j}

I have to find power flow density vector(this i know is a P=ExH pointing vector the power)
the dissipated per unit volume, the electric field energy density, and the magnetic field energy density everywhere.
 
Any help with this problem. Its due today. Thanks
 
TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
