Question

What is the value of refractive index for water and crown glass answer​

Answer 1

Answer:

1.52 index of glass crown

Explanation:

Some typical refractive indices for yellow light (wavelength equal to 589 nanometres [10−9 metre]) are the following: air, 1.0003; water, 1.333; crown glass, 1.517; dense flint glass, 1.655; and diamond, 2.417.

Answer 2

Refractive index for water = 1.333

Refractive index for crown glass = 1.517

Explanation:

The refractive index is the measuring the bending of light ray when passing from one medium to another.

• Refractive index can be defined as the ratio of the velocity of a light ray in an empty vacuum to the velocity of light in a medium.

                                         $n=c/v$

• The refractive index varies with wavelength of the light.
• Light propagation in absorbing materials can be described using a complex valued refractive index .
• When light travels in a medium other than the empty space, the atoms of that medium continually absorb and re-emit the particles of light, slowing down the speed light.
• So water has a refractive index of $1.333$

• Crown glass is a type of optical glass used in lenses and other optical components .
• So it has relatively low refractive index of $1.517$ and low dispersion.
