Light is not coherent.

On the contrary, any single frequency light, i.e. single color light, is
coherent. Most of the laser light in an interferometer is coherent.
Otherwise, steady-state interference could not be achieved.

All natural sources produce the damped waves. They are not coherent at all
frequences.

You have no clue what the word "damped" means, do you?

The Sun, which is a natural source, does not produce damped waves.

Being damped and being coherent are two independant properties.

Only today radio transmitter and free electron laser are able to produce
undamped waves.

Wrong again because you have no clue what the word "damped" means; almost
EVERYTHING produces undamped waves.

You are an ignorant, babbling, ineducable idiot who knows absolutely
NOTHING about how anything works.

Why can't you obtain and read a university level textbook on anything in
any language?

Is it because you are too stupid to be able to understand the material?

However, since you have no understanding of anything, you would be better
to start with a grade school textbook as your knowledge is that of a
five year old.
