We say that vibrations of Faraday lines of force create electromagnetic waves.Now photon is the quanta of electromagnetic field.Is photon also the quanta of electromagnetic wave? How can the same photon represent both if so?

Now photon is the quanta of electromagnetic field.
It's only when a field is changing that energy is transferred and photons are an explanation of that energy transfer. I don't think there is any conflict of meaning here.

What is the source of the information you are quoting here and in your other thread?

Had read in Carlo Rovelli's book.

Entertaining and not ‘wrong’, many popular science books are not to be used as textbooks.
If I were you, I would read a few alternative sources in addition to this book. A dry as dust textbook doesn’t go for dramatic effect like a good read but doesn’t tempt the reader to extrapolate.
