    Hello, thanks very much for offering Scholar - it's great for revising! I was looking at the Advanced Higher Physics page on Gravitational Redshift and got a little confused.
    https://courses.scholar.hw.ac.uk/vle...e-8cdcca574738

    My physics teacher was also confused about this statement
    "This effect can also be explained in terms of the photons. If a photon moves towards the Earth, the photon's energy increases as it travels to a position of smaller gravitational potential energy. Therefore, from E = hf, the photon's frequency ought to increase."
    As it doesn't match the picture below. Please can you clarify which is correct and perhaps fix the sentence/picture.
    Many thanks

    Can't open that link.

    but afaik (and I don't know much about scottish highers at all) it's not something you'd run into until probably the second year at uni cos it's a consequence of general relativity.
