In a vacuum, light travels at a constat speed. It won't get faster or slower over time. In other substances (e.g., in water) light moves at a speed determined by the characteristics of the substance. Here, it won't get slower or faster with time, either.

The greater the density, the faster the wave moves. Sound (a wave) travels faster in steel than in air. Steel has the higher density.
In a vacuum such as space there is complete silence because there are no molecules to carry the sound.When traveling through water, sound moves around four times faster than when it travels through air.The loudest natural sounds ever made on Earth are probably gigantic volcanic eruptions , such as the explosions of the island of Krakatoa.The scientific study of sound waves is known as acoustics.
earth moves through space two major ways:rotation and revolution -jerrold robinson-
No. The air that travels over the wing moves faster.
A whale's song travels faster than a bird's chirp. This is because a whale's song travels through water, where sound moves much faster than it does in air.
Depends on what they are traveling through- the denser the substance, the faster sound moves. It travels faster through water than through air. In air, the greater the air pressure, the faster it moves (denser air). The lower the temperature, faster the speed (cold air is dense). At sea level, 20 degrees Celsius, sound travels through air at 1126.547 ft/second- or about 768.095 mph

Sound is a compression wave that travels via then vibrations of particles. If the particles are closer together then the wave (sound) moves faster. Particles are closer together in a liquid than a gas, therefore sound travels faster through liquids.
No. The denser the material, the faster sound moves through it.
Light. Nothing moves faster than light
Atoms move fastest in gases, then liquids, then solids. Also, atoms move faster in higher temperatures than in lower temperatures.
Light is bluer as it moves farther is because blue travels faster than the other colors in the visible spectrum.
