alleryLight bends towards the normal on entering water. The wave model predicts its speed in water is:
ALess than in air
BMore than in air
CSame as in air
DZero in water
Answer & Solution
Correct answer: A. Less than in air
1. The particle model predicted faster light in water.
2. The wave model predicted the opposite.
3. So the wave model says slower in water.
