# Which has high refractive index core or cladding?

## Which has high refractive index core or cladding?

The refractive index of the core is higher than that of the cladding, so light in the core that strikes the boundary with the cladding at an angle shallower than critical angle will be reflected back into the core by total internal reflection.

## How do you calculate 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.

## What do you mean by refractive index?

Index of Refraction

## What will happen if refractive index of core is less than refractive index of cladding?

The cladding is made of a material with a slightly lower index of refraction than the core. This difference in the indices causes total internal reflection to occur at the core-cladding boundary along the length of the fiber. Light is transmitted down the fiber and does not escape through the sides of the fiber.

## How do you calculate the refractive index of a core?

Refractive index n1 of core is defined as: n1 = c / v, where c = 3×10 8 m/s is the speed of light in vacuum and v is the speed of in the core. Maximum size of angle t must be smaller than 21° in order to have total internal reflection at the core-cladding interface.

## What is a relative refractive index?

The ratio of the speed of light in a vacuum to the speed of monochromatic light in the substance of interest. Also called the absolute index of refraction it is commonly called the refractive index or index of refraction.

## What is absolute refractive index?

The absolute refractive index is defined as the ratio of the speed of light in vacuum and in the given medium. The absolute refractive index should never be less than 1.

## What is the dimension of refractive index?

Refractive Index is defined as the relative speed at which light moves through a material with respect to its speed in vacuum. As both the values belong to same quantity (speed), units get nullified. So Refractive Index is dimensionless quantity. Dimensional Formula of Refractive Index = M^0L^0T^0.

## Is refractive index a dimensional variable?

Refractive index is dimensionless variable.

## Is refractive index a dimensional constant?

Relative density, refractive index and Poisson ratio all the three are ratios, therefore they are dimensionless constants.

## What is dimensional formula for work?

Work = Force × Displacement. Or, W = [M1 L1 T-2] × [M0 L1 T0] = [M1 L2 T-2]. Therefore, work is dimensionally represented as [M1 L2 T-2].

## What is dimensional formula of resistance?

Therefore, resistance is dimensionally represented as M L2 T-3 I-2.

## What is dimensional formula of potential difference?

The answer is a. The potential difference is the work done per unit charge. The dimensional formula for potential difference is dimension of work/dimension of charge =dimensions of mass times acceleration times distance/ dimension for charge =M^1L^1T^-2L^1 / A^1T^1 = M^1 L^2 T^-3A^-1 HENCE OPTION "C" IS CORRECT.

## What is the dimensional formula of capacitance and resistance?

Now we can determine the dimension of RC by the dimensions of resistance(R)and capacitance(C). Therefore, the dimension formula of RC is [M0L0T].

## How do you calculate capacitance dimensional formula?

Therefore, the dimensional formula of capacitance is [M−1L−2T2Q2] .
