The speed depends on many factors, and one of the factor is friction. In denser medium (WATER) friction is more so speed is less, while in free space and vacuum friction is less speed is more, speed and friction is inversely proportional to each other.so, speed decreases in denser medium than in rare medium.
speed α 1/friction
So, automobiles like cars are applied a lubricant on its outer surface which decreases the friction and move with more speed. Now automobile companies working to reduce friction which helps to enhance speed.
If we go in depth in this topic friction is the major criteria that effect the speed. we can run faster in free space(rarer medium) than in water(denser medium) i.e.,water is in liquid state the water molecules are closely packed so it has more defensive power i.e., more friction, While in free space the air molecules are lightly packed so it has less friction.
In this way we can prove that body moves faster in rarer medium than in denser medium.
Eg: throwing a ball in water travels less distances than compared a ball throwing in free space

What happends to the wavelength of the waves as they pass into the denser medium?
The wavelength of the waves decreases as they pass into a denser medium. This is because the speed of the waves decreases in a denser medium, but the frequency remains constant. This results in a shorter wavelength.
How does the speed of a wave relate to the density of the medium it is traveling through?
The speed of a wave is inversely proportional to the square root of the density of the medium it is traveling through. As the density of the medium increases, the speed of the wave decreases. This relationship is described by the wave equation, which takes into account the elasticity and inertia of the medium.
What happens to the speed of a wave if the frequency decreases and the waveleNgth increases?
If the frequency decreases and the wavelength increases, the speed of the wave remains constant. This is because the speed of a wave is determined by the medium it's traveling through, not by its frequency or wavelength.
What happens when a wave moves through a denser medium?
When a wave moves through a denser medium, its speed decreases while its frequency remains constant. The wave will also experience refraction, causing it to change direction as it enters the denser medium. Additionally, the wavelength of the wave will shorten as it moves into the denser medium.
What happens to a sound wave when it enters a denser medium?
When a sound wave enters a denser medium, its speed decreases and its wavelength also decreases while the frequency remains the same. This causes the sound wave to bend towards the normal line at the boundary between the two media.
What happens to the speed of light as light travels though materials?
The speed of light is not affected by the density of the medium. Its the path of the light that is affected . Phenomenon like reflection or refraction take place when the light goes to different medium

When the temperature of a medium increases the speed of sound decreases true or false?
False. In general, the speed of sound increases as the temperature of a medium increases. This is because higher temperatures lead to greater molecular motion, which increases the speed at which sound waves can travel through the medium.

If the frequency decreases and the wavelength increases, the speed of the wave remains constant. This is because the speed of a wave is determined by the medium it's traveling through, not by its frequency or wavelength.

When light passes through a denser medium what happens to the light?
a denser medium hav more no.of particles also > the no.of particles > the opposition provided for..... therefore both wavelength and speed of light changes but frequency remains the same.
Why does wavelength o light decrease when enter to denser medium?
When light enters a denser medium, its speed decreases due to interactions with the medium's particles. This change in speed causes the frequency of the light to remain constant but the wavelength to decrease, following the equation v = fλ, where v is the speed of light, f is the frequency, and λ is the wavelength.
In general how does changing the temperature of a medium affect the speed of sound through that medium?
As the temperature of the medium increases, so does the speed of sound. As the temperature decreases the speed of sound decreases (this is true for air, at least). To calculate speed of sound in air: V = 331 + 0.59T where T is the air temperature in degrees C.
How is wave speed and the density of a given medium linked?
Wave speed and density of a medium are inversely proportional - as the density of a medium increases, the wave speed decreases. This is because denser materials have more particles per unit volume, causing them to interact more with the wave and slow it down. Conversely, less dense materials allow the wave to travel faster since there are fewer particles to impede its progress.
How is the sound speed and the medium related?
The speed of sound in a medium depends on the properties of that medium, such as its density and elasticity. In general, sound travels faster in mediums that are denser and more elastic. This is because the particles in the medium can transmit the sound waves more effectively.
