Question

Electromagnetic waves propagation symbol

Answer 1

Answer:

electromagnetic wave transports its energy through a vacuum at a speed of 3.00 x 108 m/s (a speed value commonly represented by the symbolc). The propagation of an electromagnetic wavethrough a material medium occurs at a net speed which is less than 3.00 x 108 m/s.

Answer 2

Electromagnetic waves are waves which can travel through the vacuum of outer space. Mechanical waves, unlike electromagnetic waves, require the presence of a material medium in order to transport their energy from one location to another. Sound waves are examples of mechanical waves while light waves are examples of electromagnetic waves.
