Question

I need help, please

Answer 1

The solution regarding the Mechanical waves and electromagnetic is discussed below:

1. The difference between the Mechanical waves and electromagnetic waves is Mechanical waves require medium and electromagnetic waves do not.
2. The example which describes the production of a longitudinal wave and the motion of particles that transport in the waveform is a single pulse tone is sent from an underwater speaker through a pool of water and the water molecules are compressed in the direction of wave.
3. The similarity between the em waves and mechanical waves are transfer matter over long distances.
4. In a compression waves, the medium is displaced in the same direction. The light bulb can generate waves and travel through the vacuum. The unique properties of EM waves are amplitude and frequency.
