- Speed of light in air (c_air) = 3×108m/s - Refractive index of glass (n_glass) = 1.5 2. Use the formula for refractive index: n=caircglass Where: - n is the refractive index, - cair is the speed of light in air, - cglass is the speed of light in glass. 3. Rearrange...
- v is the speed of light in the medium. 1. Identify the given values: - Speed of light in air, c=3×108m/s - Speed of light in the medium, v=2×108m/s 2. Substitute the values into the refractive index formula: μ=cv=3×108m/s2×108m/s 3. Perform the division: μ=32...
Mathematically the refractive index of the medium is calculated by taking the fraction of speed of light through the vacuum and speed of the light in any random medium.Answer and Explanation: Let the speed of light in water be cw and speed of light ...
The speed in speed of sound is equal to the speed in speed of light multiplied by 874,030.489796. For example, here's how to convert 5 speed of light to speed of sound using the formula above. speed of sound = (5 c × 874,030.489796) = 4,370,152.44898 sound Speed of light ...
Its value is generally measured in a vacuum. The speed of light can be determined by dividing the distance between the sun and earth to the time taken by light to reach the earth's surface. At different mediums, light wave travels at different speeds....
Sound is a form of energy, like light, that vibrates and travels in waves. When something vibrates, like a guitar string, it pushes molecules together. This creates an area of high pressure, which is called the compression part of a sound wave. As the string moves the other direction it...
Fizeau has determined the velocity of light= 193118 miles per secondby direct experiment.This coincidence is not merely numerical. I worked out the formulae in the country, before seeing Webers [sic] number, which is in millimetres, and I think we have now strong reason to believe, whether ...
First off, I'm not a physicist (as I'm sure is evident by my multi-part question), but I'm hoping someone will be kind enough to explain this in basic terms. Part the first: I'm wondering if someone can explain to me in layman's terms why the speed of light is essentially th...
Speed of light The speed of light is regularly indicated in meter per second but can also easily be converted to kilometer per hour. This speed, being the fastest of all forms in the universe, is variable and depends essentially on the refractive index of the medium in which it enters or...
The time it takes for the light from the Sun to reach the Earth is around 8 minutes. Sound moves through the air at a speed of around 343 meters per second, which is 1234.8 km/h or 767 mph (at 20 °C / 68 °F). It means that a sound wave in air needs about 2.9 seconds to...
