    Problem with diffraction equations (diffraction and astrophysics)

    Homework Statement Hey everyone. Just as a preface so you all know, I'm in England studying AQA Physics A. I'm currently studying the optional astrophysics module. I have a problem - in all the textbooks and revision guides I have, there is a topic on diffraction of light through a grating...

    Simple Harmonic Motion: Pendulum theory, trouble understanding

    Homework Statement So with pendulums in SHM, in my A level physics textbook (AQA Physics A), it shows a pendulum that has been displaced from equilibrium. It says that the restoring force is provided by the object's weight. Why isn't the restoring force provided by the tension in the string...

    Studying for old units (a-level)

    Okay, so this isn't actually a chemistry or biology homework question as such. I just didn't know where else to ask this question, if somebody could redirect me to the correct place if it's not acceptable to post this in here, that'd be awesome :) So basically, I'm studying A-level...

    Area Under Graphs: Finding Work Done

    Okay, so I've got a question on graphs and areas under curves. For example, a force-distance graph, with force on the y-axis and distance on the x-axis, where you find work done from that graph. I understand that a constant force will produce a horizontal line on the graph, like so: Force...
