should refractive index of glass change for different wavelengths of light, when they r refracted thru a prism

Question

could you please exlpain exactly HOW???

I performed an experiment via which I recieved the same angles of minimum deviation for red as well as blue light....is it okay for same readings?
otherwise, refractive index calculated would change....is that not so?

Answer 1

Yes, the refractive index of glass varies with wavelength. If it didn't, a prism wouldn't disperse light into a spectrum.

The index of refraction is always higher for shorter wavelengths. I'm not sure why; maybe it takes more time for a higher energy photon to be absorbed and re-emitted? The result is that blue light is refracted more than red light. Numbers for a typical crown glass (Bk7) are 1.5143 at 656.3nm and 1.5267 at 435.8nm.

Answer 2

The refractive index of glass (and all other materials) is a function of wavelength. The refractive index is a complex number consisting of a real part (refraction) and an imaginary part (absorption). Generally the real part of the refractive index will increase with increasing wavelength, but there are some derivative like features in the curve at wavelenghts close to absorption bands (in the UV for glass). The variation in refractive index with wavelength is called dispersion. A glass equilateral prism typically disperses light by one degree for every 60-150 nm in the visible region.

Answer 3

The refractive index of glass (and all different aspects) is a carry out of wavelength. The refractive index is a problematic quantity mutually with a real section (refraction) and an imaginary section (absorption). traditionally the real component to the refractive index will strengthen with increasing wavelength, in spite of the indisputable fact that there are some by-product like good factors in the curve at wavelenghts close to to absorption bands (in the UV for glass). The version in refractive index with wavelength is conventional as dispersion. a pitcher equilateral prism commonly disperses tender with the help of one degree for each 60-one hundred and fifty nm in the seen section.

Answer 4

no, the refractive index of glass is a constant. it does not change with different wavelengths of light. rather, the different light wavelengths bend different amounts due to how much they each react to the glass' constant index of refraction.

i believe i am correct, a little rusty on high school physics

Answer 5

Normally different wavelengths of light have different wavelengths of light.

This causes dispersion. A major problem in fiber optical communications because the light signal spreadout over time.

Answer 6

yes, of course
