poco moto means "little movement"
Medium: makeup of the performance medium/apparatus (instrumentation:specific instruments and/or voices); size of the performance medium (number of individual parts; number of performers per part).
Andante is a musical term referring to the speed at which a piece of music should be played. It means 'slowly', or at a walking pace.
The speed of light is not medium: in vacuum, it is the highest speed that there can be. Hardly a definition of medium!
c divided by the index of refraction of the medium = the speed of light in the medium.
because the density of the medium changes with temprature
The speed of sound through the medium also increases.
No, light in a medium will travel at a slower speed.
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.
It is usually expressed the other way: the ratio of the speed of light in a vacuum to the speed of light in a medium. In that case, it is called the "index of refraction".
That quotient is the refractive index of that medium.
In straight lines (well, "geodesic" might be a better term), and at the speed of light in the medium they're in.
actually medium has amain role in the speed of sound, In air the sound can move faster while comparing to any other medium like liquid ,solid
The speed of a wave is a property of the medium, changing the speed would need a change in the medium itself. If the medium doesn't change as a wave moves, the wave speed is steady. Formula: Speed = distance divided by time
No it is not true. When the temperature of the medium increases the speed of sound in that medium increases.
