What is the main difference between the Schrödinger model and the Bohr atomic model?

A) Schrödinger believed that electrons could only exist in orbits, but Bohr stated that electrons could be found anywhere in the atom.

B) Bohr believed electron orbits were circular, but Schrödinger’s equations represent complex shapes describing the probable locations of electrons.

C) The Bohr model did not explain the emission and absorption spectrum, but the energy levels described by Schrödinger explained this property.

D) Bohr believed that the electrons circle the nucleus because positive particles attract negative particles, while Schrödinger believed that an electron was a wave.

the answer is B :Bohr believed electron orbits were circular, but Schrödinger’s equations represent complex shapes describing the probable locations of electrons.

Explanation:

just took the test on edge

moving ball hits still ball. mover stops, hit ball moves. momentum transfer.

scattering of light by tiny particles in air to produce the colors we see on sky, is dependent on the following factors:

(i) wavelength of light

(ii) size of the scattering particle  

(iii) distance traveled by light through the atmosphere.

according to rayleigh's law of scattering, the amount of scattering is inversely proportional to the fourth power of its wavelength. shorter the wavelength, greater is its scattering. hence violet/blue light is scattered more than red.

sun's light is a composite light ( visible light) with wavelengths in the range 400 nm (violet) to 700 nm (red). as sunlight passes through our atmosphere, the molecules of air scatter light according to their wavelengths. during sunrise and sunset, the sun's position is below the horizon. hence light from the sun travels a greater distance in the atmosphere when compared to its position a noon.

as sunlight enters the earth's atmosphere, blue light is scattered away and at the end of its journey in the sky, only red and orange wavelengths remain in the beam.

hence at sunrise and sunset, the sky appears reddish orange.
