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.
What is the acceleration of light?
That depends on what your light ray is traveling through. If through vacuum, then its speed is 299,792,458 meters per second. If through anything else but vacuum, then (299,792,458 meters per second) divided by (the index of refraction of that material.
An object appears blue when seen in white light What colour will appear in Red light?
The simple answer is black. However, this is true only if the colour of said object is pure blue; If it has even the slightest tinge of red in it, you will see a very dark shade of red.
A wave that requires a medium to travel?
A mechanical wave such as a sound wave requires a medium to travel through.
What is it called when light moves through water?
Nothing special. But when light travels from one medium to another (from air to water for example) it is refracted. One answerer said a rainbow. A rainbow is caused by the different wavelengths (colors) of light are refracted at slightly different angles, so that we see different colors appearing at different positions.
Who said that the heavinly bodies were composed of matter not pure orbs of light?
He who knows best 0_0
Can it be said that matter turns into pure energy at the speed of light squared?
Einstein's famous equation, E=mc2, basically means that energy and mass are interchangeable - that under the right conditions, mass can turn into pure energy, and energy can turn into mass. So, in essence, it can be said that matter can turn into pure energy if it is travelling at the speed of light.
What is the difference between liquid and solid medium?
In wave motion, the media are said to be liquid and solid according to the states of media themselves, that is, if a medium is in solid state then the medium is said to be solid medium and if the medium is in liquid state, then the medium is said to be liquid medium.
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.
When is an substance said to be pure?
A pure substance is an element or a compound.

What is a photophone?
The Photophone, also known as a radiophone, was invented jointly by Alexander Graham BellHe said it was his greatest invention.It is a means of communication...through the transmission of light.
What are some tips on communication in business?
Some tips on communication in business are to be very mindful of what the communication is all about as well as what the reaction and response to said communication should be.
If traits that are passed on by parents are the same they are said to be?
Pure.
Is a carrot a pure substance?
its not a mixture because i had a test on it and it said it was a pure substance.
Who said let there be light?
Supposedly God said "Let there be light"
How do you use specificity in a sentences?
Somewhere in a sentence. Specifically, at the beginning. :D
