An example of conductors of heat would be iron pans. a example of electric insulators would be copper, gold and silver. to contrast conductors and insulators, insulators let electricity pass through them while conductors restricts electricity. both conductors and insulators can work with lithium and sodium.

The index of refraction of silicate flint glass for red light is 1.620 and for violet light is 1.660 . A beam of white light in
Alinara [238K]

Answer:

The angular separation between the red and violet components of the spectrum that emerges from the glass is 1.72°

Explanation:

Given:

Refractive index for red light n _{1} = 1.620

Refractive index for violet n' _{1} = 1.660

Refractive index for air n_{2} = 1

Incident angle \theta _{1} = 28.30°

According to the snell's law,

    n_{1} \sin \theta _{1} = n_{2}   \sin \theta _{2}

For red light,

  1.620 \times \sin 28.30 = 1 \sin \theta _{2}

Where \theta _{2} = transmitted angle for red light

   \theta _{2} = 50.18°

For violet light,

  1.660 \times \sin 28.30 = 1 \sin \theta' _{2}

Where \theta' _{2} = transmitted angle for violet light

   \theta' _{2} = 51.9°

Angular separation between red and violet light is given by,

  \theta ' _{2} - \theta _{2} = 51.9 -50.18 = 1.72°

Therefore, the angular separation between the red and violet components of the spectrum that emerges from the glass is 1.72°
