A group of students placed small objects in a ripple tank and observed the path of the water waves as they approached the obstacles. They
observed the waves bending around the objects. This phenomenon can
be observed in a harbor as waves bend around small boats. In order for
this to occur, the wavelength of the waves must be larger than the
objects they encounter.
This process is best described as –
A reflection
B refraction
С diffraction
D interference
