Chapter 30

examples from class & hw:

Generation of EM Waves (antennae)

Determining Wavelengths of EM Waves  c = (wavelength) (frequency)

Radiation Pressure Absorbed  p = I / c

Radiation Pressure Reflected  p = 2( I ) / c

concepts:

Electromagnetic Spectrum, Frequencies of Visible Light

EM Waves are transverse waves because of the amplitude is perpendicular to the direction of wave travel.

EM waves are always waves of: Fields, NOT of Matter

Any changing electric flux results in a magnetic field

EM waves carry energy, also carry linear momentum
