    Ocean waves parallel to the shore

    Homework Statement Explain, using Huygen's Principle, why ocean waves break parallel to the shore. Homework Equations None The Attempt at a Solution Okay, I know that the speed of the waves decreases as the water gets shallower. Therefore, since the frequency is the same, the wavelength...

    Reciprocal Lattices and Ewald Sphere: Solving for a* and c* in a Tetragonal Cell

    Homework Statement I have to draw a reciprocal lattice of a tetragonal cell with parameters a=3A and c=5A, a body-centred lattice. How do I find a* and c*? I also have to draw an Ewald sphere, and lamda=1.5. However, if I use my solutions (I think they're wrong, see below) I get something that...

    What is the Force Between Links in a Falling Chain?

    Homework Statement A uniform chain of length l and mass M contains many links. It is held above a table so that one end is just touching the table top. The chain is released freely. What is the force between the links? What is the time for the topmost link to fall to the table? Homework...
