Question

the refractive index of a piece of transparent quartz is the greatest for which light​

Answer 1

Answer:

Refractive index is most for violet light and minimum for red light

This is because.......refractive index=velocity of light in air/velocity in medium

Velocity in air is a constant

Velocity in medium depends on the wavelength in medium...

NOTE THAT THE FREQUENCY NEVER CHANGES

Velocity =frequency×wavelength

ref.index is therefore inversely propertional to wavelength in medium

Wavelength is max for red light....minimum for violet

Thus refractive index is most for violet light and minimum for red light
