Photons are born and die at c. They experience no time and have no frame of reference.

The loneliest of experience.

The speed of light is different depending on the medium though isn't it? So to change speed I would have thought some acceleration would have to be involved.

I have no idea what I'm talking about though.

It's not. The wave front moves slower. Because when light moves through matter it's getting absorbed and reradiated.
