Question

find expression for (1) energy density (2) intensity for one dimensional progressive wave​

Answer 1

Answer:

1. The formula for the energy stored in a magnetic field is E = 1/2 LI2. The energy stored in a magnetic field is equal to the work needed to produce a current through the inductor. Energy is stored in a magnetic field. Energy density can be written as uB=B22μ u B = B 2 2 μ .

2.Intensity is an objective measure of the time-averaged power density of a wave at a particular location. The SI unit of intensity is the watt per square meter . ... When the amplitude of a sound wave is measured by the maximum change in density of the medium in bulk, its intensity is equal .
