I know this might be very basic, but I'm really curios what will actually happen to photon if it strikes an electron and all its energy being absorbed by this electron, Does the photon cease to exist ?

I know that if the source of the photon is highly energetic, then it will give some of its energy to the electron and the photon will scatter off with lower energy. Well, you may correct if I'm wrong in this part.

If we suppose that the photon has a low frequency which means to say lower energy, and actually all of its energy being absorbed by the electron. Is it that the electron actually absorbed the photon itself, or the photon would continue to exist with Zero energy ?

Just someone may explain to me or even correct if I'm wrong on what I said.

The photon loses all of its energy to the photoelectron at once. Einstein's Photoelectric Equation shows that Energy of photon = Work function + Maximum Kinetic Energy of the electron. Hope it helped!

If something loses all of its energy and cannot interact with anything else, then its equally correct to say that it doesn't exist anymore. So either way, it doesn't exist. =)
