question 30 of 33
which of the images below illustrates refraction of a wave?

Explanation:

Refraction is the bending of a wave as it passes from one medium to another. Image B shows a wave changing direction as it moves from one medium to another, which is characteristic of refraction. Image A shows reflection (bouncing back of a wave from a surface), Image C shows diffraction (bending around an obstacle), and Image D shows a wave hitting a surface without bending through a medium - change.

Answer:

B. B
