Which of the following correctly describes refraction?.
- A.It is the bending of waves due to a change in speed
- B.It is the spreading of waves as they pass through an aperture
- C.It is the interference of two waves
- D.It is the reflection of waves at a boundary
Model answer
What a good answer should say
- It is the bending of waves due to a change in speed
Explanation
Why this works
Refraction occurs when waves change speed as they pass from one medium to another, resulting in a change in direction, which is a key characteristic of wave behavior.
