The waves created in step 6 are transverse waves. Transverse waves are created when particles in the medium move perpendicular to the direction of energy propagation. In this case, the particles of the medium move up and down while the energy of the wave moves horizontally.
When two waves that are in step meet, they combine together to form a wave with greater amplitude. This is called constructive interference, where the peaks of the two waves align and reinforce each other. The resulting wave will have a higher intensity and energy.
The first step is amplification of the sound that is picked up by a microphone. This usually consists of a basic 'pre-amp' section which brings the audio signal up to workable levels, and a secondary amplification which makes the signal strong enough to be processed by the recoding circuit.
The two key discoveries that confirmed the existence of electromagnetic waves were made by Heinrich Hertz in the late 19th century. He demonstrated the generation and detection of radio waves, which are a form of electromagnetic radiation, confirming the theoretical work of James Clerk Maxwell. This marked a crucial step in the development of modern telecommunications technology.
amplitude
Yes. Laser light is special in that all the waves of electromagnetic energy are temporally and spacially coherent i.e. the waves are in step (or in phase) with each other and travel in a thin beam which does not diverge over distance.
