pattern
Sound waves.
The lowest point on a Sound or light wave is called a trough.
propagation
Sound because it has more waves than light.
Sonographers use ultrasound sonography to produce such images. "Ultrasound" refers to sound waves with frequencies (pitch) above the range of human hearing. The system works by emitting sound waves and detecting them when they are reflected back. This is analogous to the process of viewing an object illuminated by a flashlight; light and sound are both waves and can be detected with the appropriate instruments.
Echoes of sound and images in a mirror involves sound waves and light waves respectively being reflected off a surface.

Sound waves.
no, sound and light are very different Sound is a vibration in air, light is a particle called a photon moving through the air

Propagation.
Sound is the vibration of molecules and atoms. Light is made up of things called "light quanta" or "photons." This means that sound cannot travel through a vacuum (there are obviously no molecules or atoms in a vacuum to transmit sound) but light can.
A sound bar is a special loudspeaker, consisting of a single cabinet, that creates a stereo sound. A visual representation thereof would be a visualization of the input sound, not the sound bar itself.
