1.

Electromagnetic waves
are combination of waves of electric and magnetic fields,
are created by accelerating electric charges

2.

Main properties of
electromagnetic properties
Frequency and period
Wavelength
Amplitude
Speed is constant and depends on medium (3*10^8 m/s in vacuum)
Transverse, non-mechanical
Undergoes reflection, refraction, diffraction, polarization and interference
Carry energy, and momentum

3.

Momentum of the EM wave
Relation between wavelength, frequency,
and period
Energy of a photon
