What are sound waves, light waves, radio waves etc?

I find it hard visualising how exactly these things move in waves.
A sound wave is a mechanical wave, meaning it's produced by objects that are vibrating [1]. It travels through a medium from one point, A, to another point, B [1]. The physics of waves help explain the process by which sound is produced, travels, and is received [1]. Light waves travel in straight lines and faster than sound waves [2]. Radio waves have the longest wavelengths in the electromagnetic spectrum and range from the length of a football to larger than our planet [3]. A waveform is a graph that displays amplitude or level changes over time [4]. As a matter of fact, a waveform is merely a combination of tens of thousands of discrete changes within an unimaginably short period, crammed into a short block in a sequencer [4]. All of the information we can decode from a radio wave is transmitted as a sine wave and modulated it, which is then sent via a transmitter and received by a receiver, the wave of information is then extracted [5,6].
Sound waves are mechanical waves, meaning that they are caused by objects that are vibrating (like atoms or musical instruments). [1] A sound wave is the pattern of disturbance caused by the energy as it travels away from the source of the sound. [2] Because sound waves are longitudinal waves, the vibration of particles is parallel to the energy wave propagation direction. [2] This means that as the atoms vibrate back and forth, a high-pressure and a low-pressure region form in the medium. These high-pressure and low-pressure regions are called compressions and rarefactions, respectively. [2] Radio waves are a type of electromagnetic radiation, and light waves travel in straight lines and can be detected with your eyes or instruments like cameras. [3, 4]
