Difference between electromagetic wave and mechanical wave
Answers
Explanation:
Electromagnetic waves are waves that have no medium to travel whereas mechanical waves need a medium for its transmission. Electromagnetic waves travel in a vacuum whereas mechanical waves do not. ... While an electromagnetic wave is called just a disturbance, a mechanical wave is considered a periodic disturbance.
Explanation:
*Electromagnetic waves are made up of Crest and trough. But mechanical waves are made up of compressions and rarefactions.
*In electromagnetic waves, motion of the particle is perpendicular to the direction of propogation of the wave. But in mechanical waves, motion of the particle is towards the direction of the propogation of the wave.
*Electromagnetic waves does not require a material medium to travel. But mechanical waves require material medium to travel.Thus electromagnetic waves can travel in vacuum but mechanical waves cannot travel in vacuum.
*Electromagnetic waves travel at a speed of about 300000000 meters per second. But mechanical waves travel at a speed of about 330 meters per second. Thus electromagnetic waves are much faster than the mechanical waves.
*Example of electromagnetic waves are: visible light, gamma rays, x rays, ultraviolet rays, etc.
Examples of mechanical waves are sound waves, infrasonic sound, ultrasonic sound, etc.
