Light and Heat

Wen light falls on something that particular object becomes hot.
So does light and heat exhibit in the same form. Well may be it does but i feel that they can be treated as two separate entities though linked. Light is just what enables us to see. Whereas heat must be some transfer of energy.
Light can also be said as a transfer of energy. Consider this light is electron rotating causing certain wavelengths in the visible spectrum to be emitted. When this electron collides with some other object
it will transfer all of its energy elastically to the object. Since it does not have infinite energy it should to stop or at least slow down in the rotatory motion. This should cause a change in the wavelength emitted by that electron. Now if it is in the visible spectrum we see it. If it isn't we cant
The object to which it collided should now acquire the energy transferred by the electron. This should cause the electron in the object to revolve faster than before causing hindrance to the opposing forces in the material of which the electron is a part.
This friction can be responsible for the heat liberated.
Now again if that electron is rotating and emitting in the visible region we see the a particular colour
if it stops we see a change in the colour of the object when light falls on it.
most interestingly if all the energy from the colliding electron is transferred to the object that particular electron should stop rotating and also if the electron that it collided with wastes all of its energy as heat in opposition to the material forces of bonding then we should not be able to see anything
May be this is how black holes are. Light doesn't come out well because there is no energy left
all of it just gets spent in overcoming the nuclear forces in the material making that up.
