How light travels in a single medium in terms of speed and bending of light?
In a single homogeneous medium (electrical properties constant throughout the medium), the speed of light is constant ... although less than its speed in vacuum ... and the light does not bend. Bending (refraction) only occurs at the boundary between different media in which the speeds are different, or in a single medium whose properties change gradually (like the atmosphere).
Why does speed of light change in different mediums?
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.

Why is the speed of the different colors of light in air the same?
All wavelengths are the same physical phenomenon ... electromagnetic radiation ... whose speed depends on the electrical properties of the medium in which it is propagating. Why would you think that they should travel at different speeds ?
What is another word for the substance in which a wave travels?
A medium.
Does the speed of light changes when it goes from rarer medium to denser medium having angle of incidence equal to 0?
The speed of light changes when it goes from one medium to another one with a different index of refraction. The angle of incidence doesn't influence the change in speed.
When waves travelling from one medium to another medium its speed changeswhy?
The speed of a mechanical wave depends on the mechanical properties of the medium. When the mechanical properties of the medium change, the speed of the mechanical wave changes as a result. The speed of an electromagnetic wave depends on the electrical properties of the medium. When the electrical properties of the medium change, the speed of the electromagnetic wave changes as a result.
Does the speed of a wave depend on the medium it is moving through?
Yes. The speed of mechanical waves, like sound and seismic, depends on the mechanical properties of the medium. The speed of electromagnetic waves, like light and radio, depends on the electrical properties of the medium.
What is the speed of a wave dependent upon?
The medium in which it travels.
Why is the speed of sound constant despite changing frequencies?
Speed of sound in a medium depends only on the properties on the medium.
When electromagnetic waves are moving through matter the speed of electromagnetic waves depends on?
Velocity of light in a medium depends on the electric and magnetic properties of that medium, namely permittivity, and permeability.
What is it about the nature of light that causes it to be refracted?
Refraction is the bending of a wave when it enters a medium where it's speed is different. The refraction of light when it passes from a fast medium to a slow medium bends the light ray toward the normal to the boundary between the two media. The amount of bending depends on the indices of refraction of the two media and is described quantitatively by Snell's Law.
How light travels in a single medium in terms of speed and bending of light?
In a single homogeneous medium (electrical properties constant throughout the medium), the speed of light is constant ... although less than its speed in vacuum ... and the light does not bend. Bending (refraction) only occurs at the boundary between different media in which the speeds are different, or in a single medium whose properties change gradually (like the atmosphere).
How does critical angle depend on color of light?
Critical angle of a medium depends on refractive index of the medium. Different colors of light have different wavelengths have different refractive indices.
When sound enters another medium such as a wall what remains constant?
When sound enters another medium such as a wall, the frequency or pitch of the sound remains constant. The velocity or speed of sound may change depending on the properties of the medium, but the frequency remains the same.
What is the force that re-accelerates light when it emerges from a denser medium?
The speed of light only depends on the electrical properties of the medium it's in. It's not a mass, it doesn't lose momentum or energy by plowing through a denser medium, and it doesn't need a force to accelerate it.
The properties and purposes of thioglycollate medium?
A thioglycollate medium is used for culturing anaerobic bacteria.
What is light refracted by?
Light is refracted by a discontinuity in the refractive index of the medium ... by going from one medium into another one where the speed of light is different.
