What does the slope of a veloctiy time graphy represent?
The slope represents a change in velocity, or acceleration. The acceleration is the gradient (steepness) of the line. A larger gradient means faster acceleration. if the gradient points down and is negative then it represents deceleration.
When waves move from one medium to another?
The particles compress and refract, passing along the energy. It travels faster in mediums with particles that are more tightly packed eg. moves faster in metal as opposed to wood. Also, the more dense the air, the faster sound waves travel.
Why does red light travel faster than blue light in air?
Red light and blue light travel the same speed in a vacuum, however they travel different speeds when traveling through any medium other than a vacuum. In most media, blue light has a higher index of refraction (usually denoted with the letter n) than red light. The higher the index of refraction, the slower the light goes compared to its speed in a vacuum. This relationship is governed by the following equation: v = c/n where v is the speed of light in a particular medium, n is the index of refraction of light in that medium and c is the speed of light in a vacuum. Since red has a smaller n than blue in most media, red travels faster then blue in most media. The index of refraction is determined by solving Maxwell's equations for a particular frequency and a particular medium.
Why do front load washer vibrates excessively?
Front loading washers vibrate more than top loaders because they spin faster. If leveled correctly on a firm surface, however, the vibration should not be excessive.
What causes the refraction of a wave?
The speed of light changes in the medium it is traversing - faster in air than water, faster in distilled water than glass. When a beam of light (consisting of many photons) strikes a semi-transparent or fully transparent surface, all the photons on the front of the wave hit at the same time (averaged). But if the beam is angled at the surface, the photons at the nearest edge (to the surface) slow down before the photons at the far edge (to the surface) and causes bending of the beam or wave. It is this difference in velocity that causes refraction. This is the basis for optical lenses (and human eyes), which refocus parallel light beams into a new image. Refraction of light into its constituent wavelengths is caused by light passing through a medium, typically a prism. It goes in one side of it, and the light breaks up into the different colors of the visible light spectrum. This creates the rainbow effect. Refraction is also the reason why our sky appears blue. Light energy is absorbed by gas particles in the upper atmosphere, and the blue wavelengths are absorbed the most, then re-radiated in what is called Rayleigh scattering. If you look near the horizon, it normally appears less blue. Around sunrise and sunset, the light directly from the Sun is scattered away from your line of sight, so you see more of the yellow and red light.
Light travels faster in a material with a lower index of refraction.?
true
Is it true that Light travels faster in a material with a higher index of refraction?
true
If light cannot travel faster than it does in a vacuum no index of refraction can ever be less than zero?
True ---Apex.
Since light cannot travel faster than it does in a vacuum no index of refraction can ever be less than one?
True
Which is faster a Ford or Chevy?
Too many variables to correctly answer that one.
Why does the sail boat go faster in light air?
That is not true, they go faster in high winds if the sails are set correctly.

What is is the similarities between reflection and refraction?
There really is no similarity. One is that they are wave behaviors. Reflection is when a wave bounces off an object and comes back to you. Refraction is the bending of a wave through different materials because the substances are different. Mechanical waves travel faster in solids then liquids so refraction happens.
What is faster Gum-pert or Bugatti Veyron?
Bugatti Veyron. If i remember correctly, its the fastest car.
What represents a difference between extrinisic and intrinsic blood clotting cascades?
one is faster then the other
Suppose light travels 15 times faster in a vacuum than it does in glass What is the index of refraction for glass Express your answer as a decimal?
The index of refraction is precisely how much faster light travels in a vacuum than in the given medium. In this case, 15. Or perhaps you meant 1.5, which would be more typical for glass - answers.com sometimes eliminates some symbols from the questions.
