Electromagnetic Waves: Features, Properties, and Uses

All electromagnetic waves travel with a velocity 3 x 10⁸ m/s in vacuum.
All electromagnetic waves can be reflected, refracted, diffracted etc.
All electromagnetic waves do not change their frequency when they travel from one medium to another.
All electromagnetic waves cannot deflect by electric and magnetic fields.
Within the same medium, as the frequency (f) increases, wavelength ( $\lambda$ )
