Mechanical waves travel when molecules in the medium collide with each other passing on energy. An example of a mechanical wave is sound. Sound can travel through air, water, or even solids. But the one thing it cant travel through is a vacuum. Other examples of Mechanical waves is water waves, seismic waves, and waves traveling through a spring.

Electromagnetic Waves in our everyday life

# data[].attributes.body
radio waves are used for communications , just how almost everybody has a radio to hear the news or hear music just how there is one in your car . These waves also are used to give out signals in TVs, and also to be able to communicate through your phones. These radio waves are also used for radar. Infrared waves is what gives out signals in your controls. Such as turning on or off your TV also flipping through channels. You can feal Infrared rays by touching your control remotes are warm that means these rays are coming out. Ultraviolet for the most causes pain. How? Well cancer is caused by Ultraviolet waves. x-rays can be used to see through your body and even kill cancer cells.

Electromagnetic waves travel in a vacuum. Two examples of electromagenetic waves are light and radio signals. Electromagnetic waves are produced by charged particles and vibrations.  Another word for Electromagnetic waves could be disturbance.

The mechanical waves need a medium like water, air, or anything for it to travel. An example of mechanical waves would be the ripples made in a pool of water after you throw a stone at it . Mechanical waves are caused by wave amplitude and not by frequency. These waves are divided into three categories that are Transverse waves, longitudinal waves, and surface waves.

Waves can be divided using several methods. As per medium, the waves can be differentiated as mechanical and electromagnetic waves . Electromagnetic waves are waves that have no medium to travel. Now mechanical waves on the other hand need a medium for its transmission .
