Mechanical Waves VS. Electromagnetic Waves Vs. Surface Waves
Transverse Waves VS. Longitudinal Waves
Definition of wave Rhythmic disturbances that can travel through matter. (The matter does not transfer). Energy is transported from one location to another.
Mechanical Waves VS. Electromagnetic Waves
Mechanical waves need medium (substance) to transfer, Example; Sound waves, Water waves.
Electromagnetic waves do not need medium to transfer, they can travel trough vacuum, Example; Radio waves, Microwaves, Infrared, visible light, ultraviolet, X-rays, and Gamma rays.
Transverse Waves VS. Longitudinal Waves Vs. Surface Waves
Direction of motion of particles is PERPENDICULAR to the direction of motion of wave.
Note: All electromagnetic waves are transverse waves, for example: radio waves, x-rays
Note: Some mechanical waves are transverse waves, for example: water waves, vibrating spring
Direction of motion of particles is PARALLEL to the direction of motion of waves.
Note: Some mechanical waves are longitudinal waves, such as: sound waves
They have the characteristics of both longitudinal and transverse waves.
Example: ocean waves are longitudinal, at the surface, but particles move in both parallel and perpendicular to the direction of wave motion.
