You divide the speed of light in a vacuum (about 300,000,000 meters/second) by the index of refraction, "n".

How do you find the speed of light?

Turn your light off then on, how long time does it takes. There you got the speed of light !!!! 300,000 km a sec is fast.


Why did Galileo want to find out what the speed of light was?

oh Galilieo


What speed can a infra red light reach up to?

There's no reason that infrared light should move at a speed different from the speed of any other wavelength of light, or for that matter, the speed of any other form of electromagnetic radiation. The speed of infrared light is simply the speed of light in whatever medium it happens to find itself at the moment.


What is bi-quartz in polarimeter?

biquatr polarimeter consists of two half semicircular quartz crystals,each one of them with a different orientation..of the incident light one of the cyrstals turns the light in one direction and the other in the other direction. its used for laboratory puroes in polarimeter experiments to find the specific rotation of any optically active comound using polarimeter tube apparatus.


What is its wavelength in Plexiglass where light travels at 67 percent of its speed in air?

To find the wavelength of light in Plexiglass, you need to take into account the change in speed of light. Since light travels at 67% of its speed in air in Plexiglass, you would need to calculate the wavelength using the formula: wavelength in Plexiglass = wavelength in air / refractive index of Plexiglass. Refractive index of Plexiglass is calculated as speed of light in air / speed of light in Plexiglass.

Would You find fossils in quartz?

Quartz is a mineral not a rock. Fossils can be found associated with quartz in sedimentary rock not inside the quartz.


How could you find the wavelength of light if you knew it's speed and frequency?

Wavelength times frequency is the speed. To know the wavelength, you have to divide the speed by the frequency of the light.


How could you find the wavelength of light if you knew its speed and frequency?

You can use the equation: wavelength = speed of light / frequency. Given the speed of light (3.00 x 10^8 m/s) and the frequency of the light source, divide the speed of light by the frequency to determine the wavelength of the light.


How to find the frequency of a wavelength?

To find the frequency of a wavelength, you can use the formula: frequency speed of light / wavelength. The speed of light is a constant value of 3.00 x 108 meters per second. Simply divide the speed of light by the wavelength to calculate the frequency.


How to find the wavelength of a frequency?

To find the wavelength of a frequency, you can use the formula: wavelength speed of light / frequency. The speed of light is approximately 3.00 x 108 meters per second. Simply divide the speed of light by the frequency of the wave to calculate the wavelength.


How do you calculate light wavelength to frequency?

You can calculate frequency from wavelength using the equation: frequency = speed of light / wavelength. The speed of light in a vacuum is approximately 3.00 x 10^8 meters per second. By dividing this speed by the wavelength of light in meters, you can determine the frequency in hertz.
