Question

Question about wavefront (wave+barrier diagram included)

Answer 1

When water waves approach a shallower media this will cause a change in velocity, magnitude will decrease and wave direction will move toward the normal line, therefore wave fronts (the wavelength) will decrease

Answer 2

I'm sorry but can you please show me that on the diagram? Thanks!

Answer 3

remember (wavelength above block < general wavelength) and since the frequency is set at the source of the waves a shorter wavelength will produce a smaller speed

Answer 4

Thank you!
