Want this question answered?
Sound is a longitudinal wave and a light wave is a transverse wave. Sound requires a medium to travel through but light can propagate without any medium.
A sound wave. This is because the sound wave is transverse meaning it needs a medium to travel through. Most solids will block visible light but not other types of light. The solid works best for the transverse because the atoms are close together making it easy to transfer the wave through the material.

Sound waves -- which are a form of longitudinal wave -- propagate through air and other media by compressing the molecules of the media in which it is traveling. Go to this site to see an animation of a ringing bell: http://computer.howstuffworks.com/sound-card1.htm
Sound cannot go through vaccum

longitudinal wave formed due to compressions and rarefractions of media through which sound is propogating

A light wave is priamrily energy, unless you get in to real high-end physice, in which case you can consider a particle. The light wave, being considered energy, can be drawn with the wave amplitude at right abgles to the direction of tarvel, rather like a wave on the sea. A sound wave is a motion through the air (or other media), where the actual media travels. it is actually compressed, and the movement of particles is in the same direction (longitudinal) as the path of the waves. In most cases (for physics) they can actually be considered the same, and the same equations apply to most situations, regardless of if the wave is light, sound, or a wave on the sea.

The amplitude of a wave produces the intensity of the wave. With a light wave, it is the intensity of the light, with a sound wave, it is how loud the sound is
media not suitable for the transmission of shear waves, such as fluids.
Sound wave is a mechanical wave. It means that, for propagation, it badly needs a material medium. But, light waves are not mechanical waves. They are electromagnetic waves. It does not need a material medium. It can pass even through vacuum. Sound wave is longitudinal in nature where as light waves are transverse in nature. Being transverse, light can be polarized. But, sound waves being longitudinal cannot be polarized.
Light waves travel at approx 300,000 kilometres per second, sound at approx 0.343 kilometres/second.Light waves can travel in vacuum or through some media (there is no such word as mediums!). Sound waves cannot travel through vacuum: they needs a physical medium.
