LECTURE HANDOUT: REFRACTION OF LIGHT
I. Review
Each of the diagrams at right shows a ray incident on a
boundary between two media.
Continue each of the rays into the second medium.
Using a dashed line, also draw the path that the wave
would have taken if it had continued without
"bending."
Does the ray representing a wave "bend" toward or
away from the normal when:
the wave speed is smaller in the second medium?
⚫the wave speed is larger in the second medium?
Faster medium
Slower medium
Slower medium
Faster medium
II. Qualitative applications of refraction
A. Place a coin at the bottom of an empty can or cup. Look into the cup at the coin while your partner
slowly moves the can away from you until you no longer see the coin. Now, keep your head steady
while your partner gently pours water into the cup.
1. Describe your observations. Switch roles with your partner so that you each have a turn.
Shown below are cross-sectional diagrams of the cup for when it was empty and when it was…
