Ranking of Waves from Fastest to Slowest:

1. Light wave
2. Sound wave
3. Water wave

Explanation:

Light wave:
Light waves are the fastest among the three waves listed. They travel at a speed of approximately 186,282 miles per second in a vacuum. Light waves are electromagnetic waves that do not require a medium to propagate, allowing them to travel through empty space at incredible speeds.

Sound wave:
Sound waves are slower than light waves but faster than water waves. Sound waves travel through a medium, such as air or water, by vibrating the particles in that medium. The speed of sound varies depending on the medium, with sound traveling faster in solids and liquids compared to gases. In air, sound waves travel at around 343 meters per second.

Water wave:
Water waves are the slowest among the three waves listed. These waves propagate through bodies of water by transferring energy from one water molecule to another. The speed of water waves depends on several factors, including the depth of the water and the frequency of the waves. On average, water waves travel at around 1-2 meters per second.
In conclusion, light waves are the fastest, followed by sound waves, and then water waves in terms of speed.
