Dependence of the speed of sound on the properties of the medium:
The speed of sound is variable and depends mainly on the temperature and the properties of the substance through of which the wave is traveling. For example, in low molecular weight gases, such as helium, sound propagates faster compared to heavier gases, such as xenon. In a given ideal gas the sound speed depends only on its temperature. At a constant temperature, the ideal gas pressure has no effect on the speed of sound, because pressure and density (also proportional to pressure) have equal but opposite effects on the speed of sound, and the two contributions cancel out exactly. In non-ideal gases, such as a van der Waals gas, the proportionality is not exact, and there is a slight dependence on the gas pressure, even at a constant temperature. Humidity also has a small, but measurable effect on sound speed (increase of about 0.1% to 0.6%), because some oxygen and nitrogen molecules of the air are replaced by the lighter molecules of water.

What causes light to accelerate?
Light does not accelerate. In a vacuum, light always travels at a constant speed of approximately 299,792 kilometers per second, known as the speed of light. It only changes speed when it passes through different mediums.
How does the speed of sound of change for mediums of different densities compressibilities and temperature?
The speed of sound of change for mediums of different densities compressibilities and temperature because different densities give different resistance to the sound. It blacks more of ht sound the denser the object is,, and give more when the object is less dense.
Why wavelenth changes with speed of light?
Wavelength does not change with the speed of light, nor does the speed of light change for different wave lengths. Wavelength x frequency = c (the speed of light) always for any given medium through which it travels. Greater wavelength yields lower frequency, so the speed is always the same. Speed changes as light passes into different media transparent to light, but the change in speed has nothing to do with any change in frequency or wavelength. Those are related only to the nature of the material and the particular light energies it may pass or absorb. So white light passing through a red filter emerges red because the blue and green frequencies have been absorbed by the filtering material. That change in wavelength and frequency is not related to any change in speed within the filter.
What causes the bending of light?
Bending of light is caused by a light ray going through different mediums, for example from air into a glass prism.Light would bend when it hits the glass (at an angle) then bend again when it leaves the prism.This is called refraction.The basic cause is the fact that light travels at different speeds in air and glass."Diffraction" can also cause light to bend.Another phenomenon is the bending of light in a gravitational field. This is harder to explain. The reason comes from Einstein's Theory of Relativity.
What is the refraction of light in different medium?
Refraction is the bending of light as it passes through different mediums with varying densities. When light travels from a medium of lower density to a medium of higher density, it bends towards the normal, and vice versa. The speed of light changes as it moves through different mediums, causing it to bend.
What is the change in speed called when light travels through different mediums?
The change in speed of light when traveling through different mediums is known as refraction. Refraction occurs because light waves change speed as they pass from one medium to another, causing them to bend.
Is the speed of light constant in all mediums?
Yes, the speed of light is constant in a vacuum, but it can change when passing through different mediums, such as air, water, or glass.
How does the frequency of light change as it passes through different mediums?
The frequency of light remains constant as it passes through different mediums. However, the speed and wavelength of light may change, leading to effects like refraction and dispersion.
What isThe bending of light as it travels from one medium to the next?
Refraction is the bending of light as it moves from one medium to another, due to the change in speed of light. This change in direction occurs because light waves travel at different speeds in different mediums, causing light to change direction at the boundary.
Does light slow down when passing through different mediums?
Yes, light does slow down when passing through different mediums. This is due to the interaction of light with the atoms and molecules in the medium, which causes the light to change speed.
How does the transmission of light through different mediums, such as air, water, and glass, vary in terms of speed and direction?
The speed of light varies in different mediums. In general, light travels fastest in a vacuum, then in air, followed by water, and slowest in glass. When light enters a different medium, it can change direction, a process known as refraction. The amount of refraction depends on the difference in the speed of light between the two mediums.
Why does a light ray bend when it travels from the air to water?
A light ray bends when it travels from air to water due to the change in the speed of light between the two mediums. This change in speed causes the light to change direction, a phenomenon known as refraction. Refraction occurs because light waves travel at different speeds in different mediums, causing them to bend at the boundary between the two.
Why do the path of the light ray changes as it travels through the different mediums?
The path of a light ray changes when it travels through different mediums due to a change in the speed of light caused by the different optical densities of the materials. This change in speed leads to refraction or bending of the light ray at the interface between the two mediums. The amount of bending is determined by the angle at which the light ray hits the interface and the refractive indices of the two materials.
Why does light slow down when it passes through different mediums?
Light slows down when it passes through different mediums because it interacts with the atoms and molecules in the medium, causing it to change direction and speed. This interaction results in a decrease in the speed of light as it travels through the medium.
Light travels through water when the light leaves the water it bends or?
Light bends or refracts when it goes from water to air because the speed of light is different in the two mediums due to their different densities. This change in speed causes the light to change direction.
What causes like to refract?
Light refracts when it passes from one medium to another with a different optical density, causing the light waves to change speed and direction. This bending of light is due to the change in the light's speed as it travels through different mediums.
What happens to the distance between waves (wavelength) when light passes through different mediums?
When light passes through different mediums, such as air, water, or glass, the distance between waves (wavelength) can change. This is because the speed of light varies in different mediums, causing the wavelength to either increase or decrease.
