# How do you find the refractive index of water?

## How do you find the refractive index of water?

The Refractive index of water is 1.3 and the refractive index of glass is 1.5. From the equation n = c/v, we know that the refractive index of a medium is inversely proportional to the velocity of light in that medium. Hence, light travels faster in water.

What is n12 refractive index?

n12 means refractive index of the first medium with respct to the second medium. Mathematically (n12)=n1/n2. Whereas n21 = n2/n1. florianmanteyw and 2 more users found this answer helpful.

### What does 1n2 mean?

1n2 means refractive index of the second medium with respct to the first medium.

What does refractive index depend on?

Refractive Index of a medium depends upon the refractive index of the surroundings, optical density ,wavelength of the light and temperature.

## What is the value of n21 * n12?

1

What is n21 and n12?

n12 is the refractive index while the light travels from medium first to medium second. And similarly n21 is the refractive index when the light travels from the second medium to the first medium.

### Which of the following is correct relations n21 1 n12?

a If n21 is the refractive index of medium 2 with respect to medium 1 and n12 the refractive index of medium 1 with respect to medium 2 then it should be clear that n12=1/n21 It also follows that if n32 is the refractive index of medium 3 with respect to medium 2 then n32 = n31 Ã— n12 where n31 is the refractive index …

Why do we say n21 1 n12 for a pair of media?

As the refractive index of the medium 1 with respect to the medium 2 is the reciprocal of the refractive index of the medium 2 with respect to the medium 1, their product is equal to 1.

## What is the relationship between the refractive index of two media?

The refractive index for the light going from medium ‘1’ to medium ‘2’ is equal to the reciprocal of the refractive index for light going from medium ‘2’ to medium ‘1’.

What is the refractive index of a with respect to B?

Refractive index of medium a with respect to medium b = 2/3.

### How do you write the refractive index of 1 with respect to 2?

Refractive index of medium 1 with respect to medium 2 is velocity of light in medium 2 divided by velocity of light in medium 1. The phenomenon of change of velocity of light at the interface between two media is called refraction. n12(read as n of 1 w.r.t.2)=v2/v1=(f. Lambda2)/(f.

How is refractive index of any medium A with respect to B?

Answer: law of refraction that defines the refractive index of a medium with respect to the other is given by first law of refraction known as Snell’s law. If one medium is vacuum or air then the constant is named as absolute refractive index of the medium.

## What is the refractive index of medium A with respect to medium B?

1.7

Under what condition the angle of refraction will be equal to the angle of incidence?

If both the media are having the same refractive index, then angle of incidence and angle of refraction are same. If the incident ray falls perpendicularly on the second medium, then the incident angle and refracted angle are same.

### How does the refractive index of a medium change with optical density of that medium?

We can say that optical density is directly proportional to refractive index and inversely proportional to speed of light for that given medium. Complete Answer: Thus, denser is the medium, lesser will be the speed of light as a denser medium has great refractive index value.

What is the relation between density and refractive index?

The overall increase of refractive index with increasing mass density is evident from the figure. The refractive index increases linearly with mass density when the mass density is much less than 1 g cm – 3 , but the linearity disappears for dense materials such as liquids and solids.

## Is refractive index is directly proportional to density?

Optical density is a property and refractive index is the measure of it. You must not get confused between optical density and mass density of medium. Refractive index is directly proportional to optical density.

What is difference between optical density and refractive index?

The index of refraction value of a material is a number that indicates the number of times slower that a light wave would be in that material than it is in a vacuum. So as the index of refraction value increases, the optical density increases, and the speed of light in that material decreases.

### What is optical density formula?

Optical density is defined by the equation: Density = log 10 I 0 * I 1 , For example, if the incident light intensity is 1000 units and the transmitted intensity is 1/100 of this, viz., 10 units, then the density is given by: Density = log 1000 10 = log 100 = 2 .
