Please look at the two sources that describe wave reflection.
Hyperphysics states that when a wave meets a rigid surface, it changes phase by 180 deg, such that an upright wave will reflect upright, as to produce a standing wave with the right conditions.
http://hyperphysics.phy-astr.gsu.edu/hbase/waves/standw.html#c1
I've come across many other sources like the following that show a wave hitting a rigid surface resulting in the opposite effect as above.
http://www.acoustics.salford.ac.uk/feschools/waves/string.htm
Are these two different situations? My texts books seems to support both, but they seem to be at odds with each other.
