How do different materials affect light and sound waves?
Light slows as it enters material with a higher density whereas sound waves speed up in materials of higher density. Light bends towards the "normal" as it passes from a less dense medium to a higher density medium ie air into glass. Both sound and light can be reflected from surfaces.
How does light travle in a material with a higher index of refraction?
It will usually change. Usually you would expect the speed to decrease, but note that the "optical density", i.e. the index of refraction, is not entirely related to the density (as defined by mass/volume).
In what medium the speed of light will be minimum?
The speed of light is a set speed at which all electromagnetic waves travel at in a vacuum. It is 3*10^8 meters/second... That being said, when light, or any other EM wave, travels through a medium it will slow down. Every material has an index of refraction which is the ratio of the speed at which light travels in a vacuum, to the the speed it travels in that material. If you know the index of refraction, you can use Snell's law to determine the speed light will travel through a specific medium. Every medium is different, however a rule of thumb is the denser the medium, the slower light will travel through it. For example, light travels faster in the atmoshpere than it does in water.
How is the index of refraction of a substance related to the speed of light in the substance?
The substance's index of refraction isSpeed of light in vacuum / Speed of light in the substance
Why is the speed of light medium?
The speed of light is not medium: in vacuum, it is the highest speed that there can be. Hardly a definition of medium!
Which material does light travels through the slowest?
Through water
In which medium does light travel the slowest?
In some fairly recent experiments physicists have claimed to able to stop light entirely in super-cooled sodium.
What are waves that require a medium to travel through?
Medium is of two type One is material medium and other one is non-material Material medium are air medium, water medium etc Non-material medium is vacuum or free space If material medium is essential for the propagation of the wave then that wave is named as mechanical wave. Example: sound waves If such a material medium is not a must then the wave is said to be Electro magentic wave. Example: Light waves.
Which is a comparison of the speed of light in a material compared to the speed of light in empty space?
The speed of light in any material medium is less than it is in empty space.
What happen when light travel through medium?
When light travels through a transparent medium it is slowed down according to the refractive index of the medium. Also if light is incident at an angle onto a surface of such a material, the light rays are bent or refracted by an angle at the boundary of the material, the angle again depending on the refractive index.
What is the material through which a wave transfers energy?
Thermal power plantThe term for such a material is "medium". Thus the sound of talking is carried by the medium air. The ocean waves exist in the medium water. Light is carried by the medium space. The plural is media.
What does light do when it travels from one material to another?
Refraction is what light does when it travels from one material to another. Refraction is when the light changes direction because it is passing through one medium to another.
Formula for refractive index in terms of speed of light in vacuum and speed of light in a medium?
Refractive Index= Speed of Light in Vaccum / Speed of Light in the material
What do we call the materials that refracts light?
Refraction is caused when light changes the medium that it is moving through. Therefore any material that is transparent to light will diffract it.
What is the material through which light travels (like air or water) called?
Light can travel through anything. The amount of light that gets through the material will vary depending on the amount of atoms in the target material.
How is the refractive index of one medium with respect to the otherrelated to the speed of light?
The refractive index of any substance is(speed of light in vacuum)/(speed of light in that substance) .The number is greater than ' 1 ' in any material medium.
How do different materials affect light and sound waves?
Light slows as it enters material with a higher density whereas sound waves speed up in materials of higher density. Light bends towards the "normal" as it passes from a less dense medium to a higher density medium ie air into glass. Both sound and light can be reflected from surfaces.
