Reflection, refraction, and diffraction all cause light
waves to
A) bend
B) change direction
C)stand still
D)absorb energy

B) change direction

Explanation:

Diffraction is the change of direction of waves that occurs when waves travel from one medium to another.

Reflection is the change of direction of waves when they bounce off of a barrier.

Refraction is the change of direction of waves that happens when waves pass from one medium to another.

Each of these are all the change in direction of waves.
