# How does the average speed of light in glass compare with its speed in a vacuum?

## How does the average speed of light in glass compare with its speed in a vacuum?

The average speed of light in glass is about 67% of the speed of light in a vacuum.

## How does the average speed of light compare in water glass and diamond?

Glass has a refractive index of 1.5, water 1.3 and diamond 2.42. This means that light will bend more when it hits a diamond than it will when it hits a piece of glass of the same shape

## Which interacts more with light of relatively high frequencies quizlet?

Which interacts more with light of relatively high frequencies? resonators that scatter blue light.

## What is the speed of light in air quizlet?

The index of refraction of a transparent substance is 1.7, and the speed of light in air is 3.00 xb7 10^ 8 s

## How does the speed of light in air compare with the speed of light in glass?

The speed of light traveling through a vacuum is exactly 299,792,458 meters (983,571,056 feet) per second. That’s about 186,282 miles per second u2014 a universal constant known in equations as x26quot;c,x26quot; or light speed.

## What is the speed of light in vacuum speed?

In this theory, light is described by the fundamental excitations (or quanta) of the electromagnetic field, called photons. In QED, photons are massless particles and thus, according to special relativity, they travel at the speed of light in vacuum

## Why is speed of light same in vacuum?

Glass has a refractive index of 1.5, water 1.3 and diamond 2.42. This means that light will bend more when it hits a diamond than it will when it hits a piece of glass of the same shape

## Is light faster in diamond or water?

Answer and Explanation: i.e., speed of light in diamond is slower than the speed of light in water

## What is the speed of light in water and diamond?

The speed of light in water and diamond is 2.25 xx 10^(8) m//s and 1.25 xx 10^(8) m//s respectively.

## Is the speed of light faster in diamond or glass?

Therefore the speed of light in glass is $1.63$ times greater than the speed of light in diamond. Note: The refractive index of any medium is always greater than one.

## Is light slower in water or diamond?

For example, light refracts more when it passes from air to diamond than it does when it passes from air to water. That’s because the speed of light is slower in diamonds than it is in water. The speed of light in the diamond is 125 million meters per second.
