Question 3: When light passes from air into water and bends, this phenomenon occurs because:
- water absorbs some light energy
- light changes speed when entering a denser medium (Correct answer)
- water molecules reflect the light backward
- photons lose mass in the denser medium
Correct answer: light changes speed when entering a denser medium
Refraction occurs because light slows down when entering a denser medium like water, causing it to change direction.
