## What do you understand by the statement the refractive index of diamond is 2.4 for white light?

When we say refractive index of diamond is 2.42, it means light is travelling from rarer to denser medium, and speed of light in air (vacuum) is 2.42 times the speed of light in diamond.

### What is the refraction index of diamond?

Some representative refractive indices

Name of material | λ (nm) | Refractive index no. n |
---|---|---|

Diamond | 589.29 | 2.417 |

Strontium titanate | 589.29 | 2.41 |

Tantalum pentoxide | 589.29 | 2.15 |

Amber | 589.29 | 1.55 |

**What is the velocity of light in a diamond?**

The velocity of light in diamonds is 121000 kms ^-1 .

**What is the critical angle for diamond?**

24.4º

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.

## How do you calculate 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.

### What is refractive index of a medium class 10?

Refractive index is a measure of how much speed of light changes when it enter the medium from air. Absolute refractive index is the ratio of speed of light in vacuum or air to speed of light in the medium. Refractive index of medium 2 wrt medium 1 is known as refractive index of medium 2.

**What is the velocity of light in diamond if the refractive index?**

The speed of light in diamond is 125,000 km s−1.

**What is the refractive index of glass?**

1.5

The refractive index of glass is 1.5.

## What is the critical angle of diamond if refractive index is 2?

i) The critical angle for diamond is 24o.

### How do you calculate the critical angle?

The critical angle can be calculated by taking the inverse-sine of the ratio of the indices of refraction. The ratio of nr/ni is a value less than 1.0. In fact, for the equation to even give a correct answer, the ratio of nr/ni must be less than 1.0.

**What is the refractive index of a diamond?**

We know, the refractive index of a medium is the ratio of speed of light in vacuum to the speed of light in that medium. ⇒ Speed of light in diamond is lower by a factor 2.42 relative to that in vacuum.

**What is the meaning of N in refractive index?**

The refractive index (n) is the velocity of light in vacuum divided by the velocity of light in a medium. The refractive index formula is expressed as, What is the meaning of refractive index of diamond is 2.42? The refractive index of diamond is 2.42.

## What is the speed of light in a diamond?

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. Since the refractive index of diamond is quite high, it means that the diamond’s speed in diamond is deficient.

### How does refractive index affect the bending of light rays?

A light ray will be “bent” more when going into a medium with a high refractive index than when going into a medium with a lower refractive index. Refractive index is an indication of how much the light is bent. The bigger the refractive index the greater is the bending.
