Complete the energy range values for the 1 excited state G. e. the second orbital) of Hydrogen. Use the simulator to fill out ranges 2 and range 3. The electron can be placed in the 1st orbital by manually dragging the electron or firing a La photon once when the electron is in the ground state. Note also that the electron will deexcite with time and so it may need to be placed in the 1st orbital repeatedly 1st Excited State Electron in H
Range 1 Range 2 Range 3
0 to 1.9 eV (anything less
than this energy will fail
to excite the atom)

what is the actual question though?

speed of light in vacuum is 300,000 km/s

speed of light in other mediums is given by the expression v = c/n, where c is the speed of light in vacuum and n is the refractive index of medium.

for the first medium v = 200,000 km/s

  so, refractive index of medium = 300000/200000 = 1.5

    1.5 refractive index is usually for glass. so first medium is glass.

for the second medium v = 250,00 km/s

so, refractive index of medium = 300000/250000 = 1.2

    1.2 refractive index is usually for water. so second medium is water.

for the third medium v = 0 km/s

so, refractive index of medium = 300000/0 = ∞

    ∞ refractive index is usually for opaque mediums. so third medium is opaque medium.
