Is wave speed greater in air or in water?

The fastest any wave can travel is the speed of light in a vacuum. It is known that this speed is approximately 3 * 10 (to the power 8) metres per second (m/s). In physics, this speed is considered the upper limit for the speed of all electromagnetic waves. Common examples of it include light, radio waves, X-rays, and gamma rays. You should know that no wave in classical physics exceeds this speed. As Class 11 students, you know that the medium is always important to consider when calculating wave speed, it is not surprising to know that when electromagnetic waves pass through a medium, such as glass or water, their speed decreases due to interactions with the medium's particles.

To know how fast a wave travels, it is important to know through which medium it pass through. The wave velocity or the speed at which a wave travels shows how quickly the energy moves through a specific medium. It could be air, water, or steel. We calculate waves speed in physics using the formula:
Wave speed = Frequency * Wavelength,
That is,
$v=f \lambda$
This tells us that the speed depends on how often the wave oscillates. It also shows us the distance between its crests or troughs. The speed of a wave is medium-dependent because of particle density and elasticity of the medium. For instance, the speed of sound waves is faster than in solids like steel.
