Which of these arrows would represent the path of a refracted ray of light? a. y b. z c. x d. w

Only Z represents a refracted ray because:

Refracted rays:

- Enter from one medium to another (in this case: from air to glass)

- Deviate from their original path when entering another medium of different optical density (glass is more optically denser than air)

Hope this helps :)
