Physics 212 Lecture: "Electromagnetic Waves."
Feb 16, 1998
- Electromagnetic waves are transverse, with both electric
and magnetic field components
- One can create or detect E-M waves with oscillating charges
or oscillating currents
- The electromagnetic spectrum covers a huge range
of wavelengths and frequencies
- The speed of light in a vacuum, "c", is about 3 x 10^8 m/s.
- Even at this speed, it can take light long periods of time
to travel astronomical distances
This lecture discusses material in Chapter 24 of Cutnell and Johnson.
