Preparing for L6 Physics #5: Transverse progressive waves

Click on the picture for the full panorama. These waves on the sea at Silloth are transverse progressive waves. They are transverse because the direction of oscillation (up and down) is at 90 degrees to the direction of energy propagation. It is a progressive wave because the crests move towards the shore. Progressive waves can transfer energy. NB If you look in detail, the motion of waves on the sea is perhaps a bit more complicated than I'm saying. Instead of just up and down, there is a rolling circular motion in the wave but there can't be many people who would decline to classify them as transverse.
