Light is an example of an electromagnetic (EM) wave. EM waves are transverse waves, not compressional waves.
Sound waves are compressional waves, so both sound traveling through air and water would be compressional.
Waves traveling along a coiled spring compress the coils together and spread them apart, so this is also an example of a compressional wave.
No. Green light, like all electromagnetic waves, is a transverse wave.
That would be sound.
Amplitude
Mechanical wavesMechanical waves need a medium to move through. An example is sound moving through the air. Sound is a compressional mechanical wave and the medium is the air. That's why there isn't any sound in space.
A material that something passes through. For example vibrations traveling through a metal rod. The metal rod is the medium.
Compressional waves are waves that produce compression and rarefaction when traveling through a medium. Water waves are not considered as compressional waves.
No. Green light, like all electromagnetic waves, is a transverse wave.
Sound waves are an excellent example
longitudinal wave. Example: Sound wave
Sunlight traveling through a window is an example of transmission. The window transmits light. It could also be an example of refraction, as the light is slightly bent when it travels through the window.
That would be sound.

No, compressional waves travel through liquids and gases. Transverse waves pass through solids. You may also be forgetting electromagnetic waves such as light, radio, x-rays, etc that propagate in neither of these ways and can even pass through vacuums.
