# Comparison of electromagnetic and gravitational radiation: What we can learn about each from the other

@article{Price2012ComparisonOE, title={Comparison of electromagnetic and gravitational radiation: What we can learn about each from the other}, author={Richard H. Price and John Winston Belcher and David A. Nichols}, journal={American Journal of Physics}, year={2012}, volume={81}, pages={575-584} }

We compare the nature of electromagnetic fields and gravitational fields in linearized general relativity. We carry out this comparison both mathematically and visually. In particular, the “lines of force” visualizations of electromagnetism are contrasted with the recently introduced tendex/vortex eigenline technique for visualizing gravitational fields. Specific solutions, visualizations, and comparisons are given for an oscillating point quadrupole source. Among the similarities illustrated…
