a beaker of water
the air in the room
Which of the following materials would light travel fastest through?
Plastic
Air
Water
Light waves travel the same in each one
How does the speed of light in water compare to its speed in air?
The speed is the same in water because it is constant in all mediums.
The speed is faster in water than in air because the molecules are closer together.
The speed is slower in water than in air because the molecules are closer together.
The speed cannot be compared without knowing the temperature.
