Question

The refractive index of glass with
respect to air is 3/2 Then
find the speed of light in air​.

Answer 1

Refractive index of water wrt air= 4/3

Refractive index of glass wrt to air = 3/2

Refractive index of air wrt water = 1/(refractive index of water wrt air) = 1/(4/3) = 3/4

Refractive index of glass wrt water = (Refractive index of glass wrt air) × (refractive index of air wrt water) = (3/2) × (3/4) = 9/8.

Answer 2

Ethene is made up of four 1s1 Hydrogen atoms and two 2s2 2px1 2py2 carbon atoms. These carbon atoms already have four electrons, but they each want to get four more so that they have a full eight in the valence shell
