Concept #1: Introduction to Electromagnetic (EM) Waves
Practice: You measure the electric field of an electromagnetic wave at a particular moment and find it points in the +z direction. The magnetic field points in the +y direction. In which direction is this wave traveling?
Concept #2: Introduction to Electromagnetic (EM) Waves - Speed of Light
Practice: You measure the magnetic field strength of a traveling electromagnetic wave to be 8.0×10-7 T, oriented along the +x direction. If this EM wave moves in the +y direction, what is the magnitude and direction of the wave’s electric field at that same exact spot?
