How does the speed of light change in jello?
Light travels through different substances at different speeds. The speed will changeas it enters jello from something else, and again as it leaves jello and enters somethingelse. While the light is in the jello its speed is constant. A few on-line resources that wechecked gave that speed as roughly 217,400,000 meters per second. That's about73% of the speed of light in vacuum.
Does the speed of light ever slow down?
The speed of light is different in different substances ... air, water, glass, jello, etc.
How do you measure the speed of light in jello using a laser?
You should try to check on sciencebuddies.org
How does the speed of light change when it enters the water?
That would depend what it enters from. If the light is transitioning from air to water,its speed decreases. If it's going from jello to water, its speed increases.
What happens to speed of light when light goes into air?
That depends what it comes out of. If it passes into air from vacuum, thenits speed decreases. If it passes into air from water or jello, then its speedincreases.
What is the speed of light through jello using a flash light?
A few on-line resources all cluster around roughly 217,400,000 meters per second.Note: The speed of light doesn't depend on where the light comes from.
How fast does light travel through jello?
For this to work you would need a cuboid shaped block of jello, with as flat a surface as possible and no impurities within it.Using a light source with a very narrow beam, (Ray box or preferably a Laser pointer, i suppose you would need one of a color that would show up in the jello) shine it at an angle from the normal (a line perpendicular to the plane the light is shining on) and measuring the angle of the incident beam (i) and then the angle of the beam as it has been refracted within it (r).Then calculate: sin i/sin r this will give you the refractive index.The speed of light within Jello= (1/refractive index of jello)x c (speed of light)
How do you use snell's law to find the speed of light in jello?
Snell's law combines trigonometry and refractive indices to determine different aspects of refraction. The law is as follows: (n1)(sinX1) = (n2)(sinX2); where n1 is the refractive index of the first medium, X1 is the angle of incidence (the angle between the incident ray and the normal), n2 is the refractive index of the second medium, and X2 is the angle of refraction (the angle between the refracted ray and the normal). Setting up an experiment using jello and a laser, one can determine the index of refraction in the jello. Shine the laser at an arbitrary angle and record this angle. Then measure the refractive angle seen in the jello (this is the angle between the ray in the jello and the normal). The index of refraction for air is 1.0003. Now substitute all three values into Snell's law and solve for n2, the refractive index of jello. An index of refraction is defined as the speed of light in a vacuum divided by the speed of light in a medium. Once n2 is determine, use the following equation: n2 = c / v. Substitute n2 and the speed of light in a vacuum (which is approximately 299,792,458 meters per second), and solve for v. The value obtained will be the speed of light in jello.
What might cause the speed of light to vary?
The speed of light varies depending on what kind of material it's traveling through. It's fastest when in vacuum, and it's different, and slower, in air, water, alcohol, oil, glass, jello, etc.
Is speed of light all different speeds?
As long as it stays in one medium (substance), the speed of all wavelengths of visible light is very close to the same number. It only changes when the light crosses into a different substance, like going from air into water, or from glass into jello.
What makes jello glow?
Glowing jello glows because of the quinine that absorbs light from the black light
Why does a red laser not pass through green or blue Jello?
The secret is explained by the titles "green jello" and "blue jello". Green jello is green because any color of light other than green light is absorbed by the jello, and the only light that remains free to scatter toward your eye is the green light. If no green light shines on it, no light at all will leave it, and you'll perceive it as black. Blue jello is blue because any color of light other than blue light is absorbed by the jello, and the only light that remains free to scatter toward your eye is the blue light. If no blue light shines on it, no light at all will leave it, and you'll perceive it as black. Any red light entering either of these quivering samples is absorbed, and nothing comes out the other side of either one.
