The terminology is the same for all waves, including light - so reflection or refraction depending on what you mean by change of direction. Firstly thanks for answering, I meant if you had water waves travelling from deeper to shallower water. The wavefront change direction when entering the shallower. so http://wiki.answers.com/Q/What_do_you_call_the_change_in_direction_of_a_wave_at_a_boundary" The effect is the same as bending of light as it goes from air into glass, for instance, it is refraction.
