Energy Density
Electromagnetic waves are made up of Electric and Magnetic fields. Which field contributes more energy or do they contribute the same? What is the total energy in an EM wave? And how can analysing capacitors and inductors lead you to estimate the energy of EM radiation from the SUN!!
Let's explore all of this!
