Can light travel from equator to the North Pole? Since light travel through a straight line, and the surface of the earth is not flat?

No. Not directly. A radio at the north pole can't receive a signal from the equator, unless it bounces off a satellite. That is why we have communication satellites.

No a light beam travels in a straight line. A light beam shined from the equator will ont reach either pole unless it is reflected by some object above the Earth like for instance a satellite.

The earth has a curvature of 1/6 x10^-6 per meter.Light can actually bounce off the atmosphere but would attenuate at the poles

It will not. We need a reflectors in the sky. This is done by satellites. Light is also scattered. This may send very a fraction of light to the north pole.

Not visible light but low frequency radio (which is essentially light) can refract and reflect off regions of the sky such that it can get to places that are not line-of-sight.

If you took a large sphere (beachball sized) and placed an led on the surface of the equator of the sphere, you could easily see that the light would not be seen at the north/south pole because of the curvature of the sphere. Gravity can bend light, but in this question you are asking the simple notion of light arcing on it's own.

I suppose if the light is strong enough then yes.

Photons travel in a straight path, provided that they don't pass near anything massive. The answer to your question is a hard, "No." Even if there was nothing blocking the path, the light would only be visible for so far and then it'd be gone.

Sure... via fiber optic cable and appropriate optical repeaters... or bounce it off the mirrors on the moon left by one of the Apollo trips...
