Light and sound waves both share what characteristic? they both exhibit the doppler effect. light and sound are both transverse waves. they both move fastest in water. light and sound both require a medium in which to travel.

(Light and sound both require a medium in which to travel)

Explanation: Sound and light always have the means to travel and get somewhere as fast as possible. Light is always faster than sound but it does not matter because they both almost always get where they want.

Part 2.   light was composed of particles or waves, a wave-particle dual nature soon was found to be characteristic of electrons as well. The evidence for the description of light as waves was well established at the turn of the century when the photoelectric effect introduced firm evidence of a particle nature as well. basically when light hits a metal object . :)

- They both exhibit the Doppler effect.

Light and sound are both transverse waves.
