When waves approach an irregular shoreline, do the waves refract (bend) towards the parts of the coastline that stick out  (headlands/shallower water)?   Or do the waves refract (bend) towards the parts of the coastline that are recessed  (bays/deeper water)?   choose one Waves do not refract (bend) along irregular shorelines. Waves refract (bend) toward bays/deeper water Actually wave refraction (bending) depends on water temperature - not water depth. Waves refract (bend) toward headlands/shallower water.

Engineering Drawing

Technical drawing has been around since ancient times. As in the ancient Renaissance, complicated drawings were created, including Leonardo da Vinci's drawing. Modern engineering drawing, including its specific orthographic projection with scale conventions, began in Europe (France) during the early stages of Industrialization. L.T. C. Rolt also made some of Marc's drawings for its block-making machinery (in 1799) that also may have contributed significantly to British engineering technology. Since he learned the art of presenting three-dimensional(3D) items in a two-dimensional(2D) plane, as we now term mechanical drawing.
