What are electromagnetic waves?
Oscillating electric and magnetic fields that propagate through space.
Define transverse wave.
A wave where the oscillations are perpendicular to the direction of energy transfer/wave propagation.
What is a plane wave?
A wave with flat wavefronts and constant phase.
Define wavelength.
The distance between successive crests or troughs of a wave.
What is the electromagnetic spectrum?
The range of all types of EM radiation, ordered by wavelength and frequency.
