The refractive index of a diamond is about 2.4. To calculate the refractive index you divide the speed of light in a vacuum by the speed of light in…

## How do you find the refractive index of a diamond?

(D). 0.75. Hint – The absolute refractive index of glass can be obtained directly by using the formula, μdg=μdμg, here μdg is the refractive index of diamond with respect to glass, μd,μg are the absolute refractive index of diamond and glass. Formula used – μdg=μdμg.

## What is the formula for calculating refractive index?

Refractive index is also equal to the velocity of light c of a given wavelength in empty space divided by its velocity v in a substance, or n = c/v.

## How do you find the refractive index of diamond with respect to glass?

Refractive index of diamond with respect to glass, μdg=1.6⇒μdμg=1.6⇒μd1.5=1.6∴μd=1.5×1.6=2.4. Q3. Q4. Refractive index of diamond with respect to glass is 1.6 and absolute refractive index of glass is 1.5.

## How do you find the refractive index of diamond with respect to water?

Refractive index of diamond w.r.t water is say n = Speed of light in water / speed of light in diamond. Inverse Ratio of refractive index of water and diamond. n= 2.42/1.33 = 1.82 (approx.)

## What is meant by refractive index of diamond?

The refractive index of diamond is 2.42. This means that the speed of light in a diamond will reduce by a factor of 2.42 compared to its speed in air. In other words, the speed of light in a diamond is 1/2.42 times the speed of light in a vacuum.

## What is critical angle of diamond?

The critical angle for a diamond-to-air surface is only 24.4º, and so when light enters a diamond, it has trouble getting back out.

## Why do we calculate refractive index?

Since the refractive index is a fundamental physical property of a substance, it is often used to identify a particular substance, confirm its purity, or measure its concentration. The refractive index is used to measure solids, liquids, and gases.

## What is refractive index?

The refractive index is the measure of bending of a light ray when passing from one medium to another. It can also be defined as the ratio of the velocity of a light ray in an empty space to the velocity of light in a substance, n = c/v.

## How do you find the refractive index of Class 10?

The refractive index formula is given as follows:

- n = frac{c}{v}
- Nm = frac{n_{a}sin i}{sin r}
- Nm = frac{sin i}{sin r}
- Above all, nm = frac{c}{v} = frac{speed of light in the vacuum}{speed of light in the medium}

## What is the refractive index of diamond with respect to bromine?

## What is absolute refractive index of diamond with respect to glass is 1.6 and absolute refractive index of glass is 1.5 find the absolute refractive index of diamond?

⇒ μdiamond = 1.6 × 1.5 (μglass = 1.5). Hence the absolute refractive index of diamond is 2.4.

## What is the refractive index of glass with respect to water?

Refractive index of glass with respect to water is (9/8) .

## What is the refractive index of glass?

The refractive index of glass is 1.5.
