An example of refraction<span> is when </span>waves<span> approach a straight shoreline at an angle. The part of the </span>wave<span> crest closer to shore is in shallower water and moving slower than the part away from the shore in deeper water. The </span>wave<span> crest in deeper water catches up so that the </span>wave<span> crest tends to become parallel to the shore.</span>
The magnification of the drawing made was 10 because it had a length of 100mm and originally had a length of 30mm. It can also be said that the magnification is 3 since dividing by the original length (30) we get: 100/30 = 3.
Birds and bats have homologous limbs because they are both ultimately derived from terrestrial tetrapods, but their flight mechanisms are only analogous, so their wings are examples of functional convergence.
