Does the index of refraction of a piece of glass depend on the wavelength of light passing through it?

The index of refraction is a ratio; if a wavelength of one wave is different from that of another wave passing through the same medium, the index of refraction should not be different for each wave, since they would have had different wavelengths in a vacuum too.

How does the refractive index of the medium depend on i the wavelength of light used ii its temperature?

Refractive index of a medium decreases with the increase in temperature. With increase in temperature, the speed of light in that medium increases; thus, the refractive index (= velocity of light in vacuum/velocity of light in medium) decreases.

How refractive index of a medium depend on the wavelength of the light used?

Refractive index of a medium decreases with increase in wavelength of light. Refractive index of a medium for violet light (least wavelength) is greater than that for red light (greatest wavelength).

How does the refractive index of a medium depend on its temperature?

Refractive index of a medium decreases with the increase in temperature. With increase in temperature the speed of light in that medium increases; thus the refractive index = velocity of light in vacuum/velocity of light in medium decreases.

How does refractive index of a medium depends on its temperature?

Does refractive index depends on the density of medium and wavelength of the light?

This change in the speed of light causes it to bend, which is simply referred as refraction. Higher the change in wavelength higher will be refraction. Hence the refractive index of the medium is directly dependent on the wavelength.

What is the relation between refractive index and speed of light?

The refractive index of a medium (n) is equal to the speed of light (c) divided by the velocity of light through the medium (v). Rearranging the equation allows us to see the relationship regarding v. The lower the refractive index, the faster the velocity of light.

What is the relationship between wavelength and refractive index?

The refractive index n is the ratio of the speed of light in the vacuum to the speed of light in the medium. Now, while the speed of light in the vacuum does NOT depend from the wavelength, the speed of light in a medium depends from the wavelength; thus the refractive index depends from the wavelength. This phenomenon is call light dispersion.

What is an example of dispersion of the refractive index?

For example, the refractive index of a glass increases as the wavelength of incident light gets shorter. The dispersion of the refractive index is often shown using the example of white light splitting while traveling through a prism.

How do you calculate the refractive index of a photon?

The refractive index for photons with a certain wavelength is n ( ν) = c 0 c m ( ν) with c 0 being the speed of light in vacuum (equal for all wavelengths as far as we know) and c m ( ν) the speed of a photon of a certain frequency ν in the material. Using c = λ ν (and assuming constant frequency) you will arrive at the expression you were using.

What percentage of light is reflected when it hits glass?

For normal incidence, approximately 4 \% of the light is reflected; this value is determined by the refractive index of the glass. When a beam of light hits a glass surface, part of the beam is reflected and part is transmitted.
