Answer

Explanation:

Step1: Compare light - wave speeds

Compare the light - wave speeds in wood (0 km/s), water (226,000 km/s), helium (299,000 km/s), and vacuum chamber (300,000 km/s).

Step2: Identify the fastest medium

The highest speed is 300,000 km/s in a vacuum chamber. A vacuum is not a state of matter but an empty space.

Step3: Identify the slowest medium

The lowest speed is 0 km/s in wood. Wood is a solid.

Answer:

  1. Vacuum Chamber; Not a state of matter
  2. Wood; Solid
